My daughter absolutely LOVES the Imagination Movers, so it was an obvious theme for her birthday. I'm not gonna lie, I love them too, so when I realized there were no Movers themed party supplies and such I needed to improvise. It was an Idea Emergency!
It's a scratch cake baked in a guitar pan with a few modifications. Some creative use of fondant, and voila! Dave's Bass, uh, I mean Bass. :)
