As a kid, I had two that were pretty equal:
in reply to My favourite stuffed toy is a(n)
- A mouse (almost all the fur had been worn off and my mom replaced the tail at some point) It's now sitting up on a dinner plate rail in my house (away from the stuffed-toy-killing dogs)
- A teddy bear made from an old fur coat (circa WWII) again, almost all the fur was worn off although a lot was gone before I got it (used to belong to my mom). It now sits in a place of honour at my parent's house.
As an adult, I would say either Dust Puppy or Tribbles
