When I saw the after pic I wanted to cry!!! I have done a few of the 3D Elmo cake (but all in cake) and I know first hand how painful getting all that hair on really is!
Here's some tips about RKT that I learned from someone here on CC and they have been very useful.
* Crush up the RK a bit before mixing to minimize the amount of air/space.
* Use only 1/2 of the butter suggested in recipe.
* Use tons of pressure when making your shape.
* Leave your item dry for at least a day or more (I think someone already posted this tip).
Good luck next time! (and btw...I think our husbands must be related...for the longest time I thought he was just staying up while I worked on cakes bc he was such a great DH- lo and behold he was just waitin' around for scraps!)
LMAO~!! Perfect time for halloween ... did you let the marshmellos dry??
OMG, Poor elmo!! ...and I was just talking to you about elmo the other day! How long did you have your RK's in the fridge?? The only time mine have fallen apart is when I put them in the fridge.
I've done a RK elmo head before and it held up totally fine and even travelled for 1 hour for delivery, so I know it works. I was really happy with the RK head actually. It was light and stable and easier than carving styrofoam.

this is the funniest thing I have ever seen. I literally can't stop laughing. WHAT is RTK, btw? Oh, I feel bad for you, know how you feel, and I am SOOOOOOO glad you shared!!!!
OHHHH rice crispy treates!! I had no idea what in the world that gross stuff was!
How did that happen!?
I don't think I've EVER laughed so immediately hard at someone's bad luck. But HAHAHAHAHAHA!!!! There's just something so wrong looking about it. Like poor Elmo just got mauled!!!!
Okay, now that I've all but peed myself laughing at that horrible incident, let me say that it definitely looks like you just didn't pack it well enough. I'm like all4cake, I pound the crap out of mine to get it packed in good. I've been doing a lot of work with them lately and that really helps set it up.
Okay, I've gotta go look at that pic again. I think I'll save this for when I'm having one of THOSE nights and need a good laugh!!!
OMG I couldn't stop laughing at Elmo. You know how people like to put the cartoon characters that kids watch on their web pages doing naughty things? Well I could so see these pics up there because Elmo looked like he got a few too many drinks in him and puked all over the place.

The second attempt is when I put his head in the fridge, but the pic is of him the first time. The second attempt he basically was deteriorating in front of my eyes so I yanked his head off and threw it in the trash lol. For some reason about 30 min after putting the bc on he became extremely soft!!

Oh it was tough to digest at first but tears soon turned to laughter. The toughest part is that I will find out next week if I have that carpol tunnel (spelling?). Omg my hand throbbed trying to get his fur on. It took forever.
Thanks for all the compliments on the elmo that was all in one piece....ok this one was def a learning experience lol. I would MAYBE one day like to try another. But I will def NOT put his head in the fridge, leave the eyeballs on the table so hubby can eat them. I WILL bang the crap out of the RKT, use less marsh and butter, let the RKT dry for a day or 2. And last but not least lock my bedroom door so that my son cannot tell me that elmo bit the dust. Thanks to you all once again for your help and suggestions. Your a pretty awesome bunch of people........and for all of you sitting in wet britches from laughter..time to go change them. lol
OMG! I wasn't expecting that second picture to look quite like that. What a disaster, but I have to say, I laughed harder than I have in a LONG time! (Not towards your mishap, but just the appearance of it all.) My first thought is that it did look like puked oatmeal.
My girlfriend was sitting next to me, and she said I'm vicious and cruel for laughing like that!
I'm so sorry Elmo fell apart. I hope you were able to repair him. He was adorable.. until the fatal accident.
Oh man, this feels like deja vu! Same thing happened with my RKT's as well....it just went kablooey!
Oh, that is the funniest thing I've seen in quite a while! when I've used RKT, I've let them set up at least a day, if not more, so they are very solid before I begin decorating on them. Good luck with your next try & thank you for giving me a good laugh!
I couldn't help but laugh out loud (sorry) when I saw the second picture, my husband turned around from his computer and said "What's that?" and I told him it was a rice krispy treat (he wouldn't have known what rkt was) Elmo and he said "Well, I guess he snap, crackled and popped"
That made me laugh even harder.

tripletmom- that was great! I hate to laugh at your mishap, but that is too funny. Very appropriate for Halloween or those parents that are tired of Elmo. At least he's not as bad as Barney! 
Now there's two Elmo's? I'm beginning to think there's a serial killer on the loose. Time to start rounding up the suspects...
Big Bird-Is he jealous because Elmo's more popular?
Oscar the Grouch-Did Elmo's nauseating happiness finally get to him?
Cookie Monster-Did Elmo steal the last cookie?
Bert-Was Elmo spending too much time with Ernie?
Oh, I'm mean. I love Sesame Street and I love Elmo...so sorry this happened to you guys. I would've been in tears. But since it didn't happen to me I can LMAO 
Better luck next time

You guys are keeping me laughing. Snap Cracke & Pop, the SS SCI Crime Team, oh man I haven't laughed this hard in a long long time. Sorry I know you two put alot of hard work and time into Elmo but the more I read these comments the more and the harder I laugh.
This is unbelievable. Can RKT really expode? Both Elmo's look like they really exploded. In tripletmom's picture you can even see what looks like red on the wall, and his nose blew out in the front.
I picture RKT sllllooooowwwwly and stickily falling, like in slow motion. That is what you would expect to happen but these things look like someone put a firecracker in Elmo's head.
You guys may have discovered some previously unknown chemical reaction...I can just see the headlines in Science Digest:
Rice Krispy Treats formed in the shape of Elmo's head have just the right chemical properties and molecular bonds to make them conducive to combustion. 
It is really the strangest thing.
I am so sorry for your RKT. I am so sorry for poor Elmo. I loved Elmo. He was my favorite annoying character on Sesame Street when the kids were little.
Your exploding head reminded me of my exploding pumpkins. Every once in awhile, I get ambition in the Spring time to grow those giant pumpkins. You know which ones? Those monstrous 2-500lbs suckers. Well, its hard to do in my town because when the hot weather hits, it REALLY hits. And it gets blazing within a matter of days!
So one year, I was watching two really, really nice sized giants. They were growing just perfect! Wonderful specimens. Little to no bugs, too (a major deal.) Beautiful pumpkins. Just beautiful. I babysat them with tender loving care.
And then the hot weather came. And it just came on fast! I had sprinklers, soakers, water, everything I could come up with. I used my beach umbrella to shade the pumpkins. I tried boards. Just everything. And they were still growing very rapidly.
Till one morning. "Pumpkin Shrapnel."
I woke up to pumpkin guts everywhere. I thought the neighbor kids had played a practical joke on me and annihilated my precious babies! I cried and cried and cried! Silly me to cry over a massacre! I told my work-buddy about it, and he stared at me and told me "They exploded, you silly girl! The hot weather made them heat up inside and explode."
And now I just laugh my silly-girl cake patootie off when I have to retell that story!! Hee hee, it was indeed a very messy pumpkin patch!!
I hope you find solace in our humor towards your mishap.
I knew fruit could do that. We woke up one night to sound of an explosion and then a terrible smell followed it. A seemingly innocent looking watermelon on the counter had just exploded! It looked normal on the outside but had apparently fermented on the inside until it just blew up. It was huge, stinky mess!
But RKT? That was what happened to me KathysCC when I tried to make a RKT character too tall, she slowly fell stickily apart...
I do wonder what made the Elmo's explode though...
This is so funny im at work sitting here with my door shut trying not to laugh so loud that my Boss will hear me, and then the eyeball thing, im still laughing, by the way what is Rtk or what everr the heck its called and what did you stuff his head with looked like carmel corn.
O.K. I have to tell you guys this I was in our local Wal-Mart and I saw Elmo, and right there in the isle I started laughing I could not stop. I know the customers thought I was crazy. A sales-person came up and just looked at me, I just looked her in the eyes and said "Forget it you would never understand". I am so afraid I will never look at Elmo the same way as I did before this thread.
OH MY GOSH... at first I read this and thought aww you poor thing all that work, THEN I read on I have proceeded to spit my soup all over the computer desk and laugh so hard it brought my DH in the room to ask what was wrong. With every post I laughed harder. THEN went back and looked at the pics again you have given a whole new meaning to Elmo. I too can see my self at the store cracking up with the flash backs of the pics and comments. Such a great family here at CC. I am really sorry snicker snicker Elmo's head umm blew up maybe he blew his nose to hard hehe.
I have had a couple of disasters with RKT myself.
I have learned:
1. Use NO butter in the recipe--just marshmallows and RC
2. Crush the RC to make your finished product as firm as possible
3. Allow the RKT to set up for a while---at least a day.
4. If #2 is not an option, cover with Royal Icing and allow that to harden for about an hour or two.
then proceed with fear and trepidation...
