I have this cake to do for a first birthday and they want me to duplicate the piggy aka monkey bank. I have a pretty good idea on how i should do it but i wanted to make sure. It has to travel a hour in the car so should i assemble there?

Any help is appreciated!!

I'm not sure how I would do it but that is going to be a really cute cake

I would not assemble at venue

Pick a good dense cake suitable for carving - not light fluffy sponge.

Start off with a board with a central dowel (long enough to go through base - to neck and at least 3/4 of way up head) glued in

Place bottom cake on board (pre-drilled with hole to fit over dowel)
Carve to shape (up to the neck area)
Crumb coat - I would use ganache, but you might prefer soemthing else
Place over dowel
Cover with fondant - smooth
Place skewers in to support head - cut to length
Make head on a separate board (pre-drilled with hole to fit over dowel) -
I'd probably put another board in head across widest part (pre-drilled again)
Carve to shape - cover with fondant
Add fondant + tylose ascents eg. arms etc

It will travel fine if done like this - I have shipped 3D cakes air-freight without them shifting

Wow those instructions are amazing!! Thank you very very much! I will post a picture when finished!!!

Don't know how many you want it to serve but if it's not a great number I would do the head with RKT, eliminates a top heavy problem.
