I think I wouldn't use chocolate bears next time, because the color is quite bold. Using the lighter colored bears and not fancying up the wheels, might be better.
For this particular baby shower I tucked two bears into some of them, since we were celebrating the birth of twins. For the cupcakes, I used the carrot cake recipe and cream cheese frosting with extra confectioners sugar. I think Judys' pineapple cupcakes would also go over well, or any other cupcake of your choice. (click on highlit names to view these recipes)
