Boo Boo bunnies are a blast from the past!  A thin, terry wash cloth is folded to resemble a bunny and has a plastic ice cube set into the belly.  Freeze your bunny and he's all ready to fix up the next "boo boo".

Bunnies come in both small and large sizes and include a poem...

"If a boo boo has you feeling crummy,
Stick an ice cube in my tummy.
  Hold it to your boo boo tight,
Soon everything will be all right!"
