Hi,

The game I am trying to remember is a PC game, played it around the early 2000's. It started with these kids that were at school and it was bring your pet to school day. All the pets got lose somehow and these two kids and a dog try to rescue them all. The world though turns into a outer space version of everything. The dog gets like three eyes and stuff, and the other animals get alien like features. I remember it was a similar set up to those games like Freddy the fish and pajama sam in terms of looks. Please help if you can!
