I thought Mr Bill was designed to attract people, but it turns out he's our two dogs' favorite toy!  They're working on dismantling and disemboweling him, but surprisingly enough he's lasting longer than any of their other toys.  We just ordered a spare for the day the original turns to scrap, and when the dogs heard the "Oh, No!" when we unwrapped him, they came running, and we had to hide him for that future day!
