Ringo and the pod

I have a guinea pig called Ringo and he's a really cheeky little thing. He has this green pod, which he goes in as his little hide out and sometimes he tips it over from pushing it to hard with his nose. He did this the other day and he kept running back towards the patio door. Someone went out to him, thinking that a cat had jumped down into the garden and was scaring him. That wasn't the case though, he was only trying to tell someone his pod had been overturned and someone had to come and put it right!
