Sassy: Which One?

Sassy found that plastic empty bottle fun - a cheap toy till it gets flattened and you throw it out to start again. It makes tons of noise and the Havanese adore it.

She was inbetween this stick that makes a tweety toy that's laying in the bed (it's a cat toy that used to have cloth hanging off of it) and that bottle and she's trying to figure out which one.
