Is it normal that my 4-year-old cousin has a teddy bear that screams

Yes. It teaches you not to hug people too hard because they will die. They will die a death..of love :| A cuddly, adorable death.

If only Lennie had this toy...

you found Ted

I don't think it's inappropriate, though a bit strange

I have a sex doll that does the same thing.

my sister used to have a Mr clumsy doll that said ow when you threw it or dropped it it was hilarious

That's one cool teddy bear

Sounds like your cousin's been playing the Charlie Charlie game

Lmfaooo wtf is it alive?

Burn it.

LOL! That sounds creepy as fuck.
