Big Sid in the guinea pig playground

Well, it's cold out there and Big Sid, Sybil and Moschops can't go outside for fear of them catching cold. So, they are treated to the guinea pig playground in the hallway or kitchen so they can stretch their legs and have some fun - must be boring staring at the cage's four walls when I'm at work.

Only Moschops has discovered how to climb stairs. Big Sid is too big and Sybil is too timid.
