Ha ha! Tink loves those too. I call them her "footballs."
We have a game we play with it every night. She brings it to me and puts it at my feet and waits for me to say "Do ya wanna play some football?" and then she grabs it and runs as fast as she can to the other side of the room. I "steal" it back from her and then kick it with my feet to her. Back and forth we go til one of us (me

) gets tired and defaults. She loves these cause they are soft and VERY squeaky and they bounce at angles because of the little feet on them.
PetSmart has them.
