The "P" family are very very dear friends of ours and their daughter is a few months younger than my older daughter. The two girls have pretty much grown up together and they get along perfectly. Miss Bekah's 4th birthday was complete with a double-layer half-sheet cake in classic white with buttercream icing. The pink character is "Foofa" from the preschool show "Yo Gabba Gabba", also in buttercream.
(Note: I usually don't do double-layer sheet cakes, this was a special exception)
