I was planning on making a 2 tiered castle cake for my niece's birthday (her party is "Disney" themed). I was hoping to put some of her favorite characters on to the cake. I am still a beginner when it comes to fondant, so I don't plan on trying to make the characters that way! Any ideas? I was thinking about just using little toy figures, but was also unsure where to get a collection of all of her favorites in one place...

Toys are fine and she can enjoy them later.  I have not a clue where to find children's toys!
