I believe it was called the Ice-Tickle (Icicle?) Bear...i would put mine in the freezer and his stomach would turn a different color and then I'd take this heart piece off his necklace and it would take him back to his regular color.

Oh my gosh, I've been looking online for this thing for years now, and you're the first person I've encountered who has mentioned this bear! I had one, too, and I am also obsessed with finding it! I described mine almost exactly like you did yours, so I know we're talking about the same thing. I'm gonna check out the "Ice-Tickle," but I don't think that's it. If you happen to find one, feel free to email e_micetro(at)yahoo. Good luck!

OMG! !! FINALLY someone else is looking for one! Mine was blue!! They were called 'Icicle Bears', I'm 100% certain. I was obsessed with putting it in the freezer before bed . Haha I want to find one so bad but I'm loosing hope! :( I can even find anyone who knows what I'm talking about! You 2 are the only ones! Ill keep u posted!:)

I have one!!!!! I love them. So cool.... Its in my attic, now and again i put it in water and watch it change colour.

ha ha so funny just been telling my husband about a hippo teddy i had that changed colour in water he cant remember them and for some reason i thought they were called yucca ducks?searched the net and coulnt find them then found ur comments!im going to check that hello color out now!:)

I knew this bear existed! I've been looking for them for years. I loved mine when I was little!Rawrr I'm excited!

I have the Hello Kitty version--never got her wet though.

Oh my goodness!! I was just telling my 3 year old daughter (who is obsessed with all things hello kitty!) about this color changing HK I had when I was a child, and she wants one in a bad way! Does anyone know where I can find another one?! Mine was lost long ago:(

I still have my little puppy version of this toy. Its so old/well used that all it's fur is peeling off! Wish you could still buy these. My kids would love them!

I had a cow that did the same thing. Had it since I was a kid and my little girl fell in love with it. It changed colors just like these when hot /cold/ or dipped in water. Unfortunately my dog got him and there is no way to fix him. Very sad... my mom even shed a few tears. Looking to see if I can find another one.I called him moo moo. What a special cow. Any information would be appreciated.
