Title--- Snowball and his Pals

Question--- Did Snowball's friends abandon him?!

Answer--- Not intentionally but yes.

Evidence--- Molly

Theory--- When they saw that they had been spotted by the little girl known as Molly, Snowball's pals Tattoo, Bearded Dragon and Derick panicked. They didn't want to be taken by a human after whatever happened to them in the past. With nothing else in their minds, they left. Unbeknownst to them, Snowball was still on the surface. Snowball doesn't seem to mind though once he hears that he's gonna be loved "forever and ever and ever!" All three of the Flushed Pets, plus many more, can be seen at Leonard's party at the end of the movie with Snowball so it appears that they're on good terms.
