Meet the hedgehog who looks a bit like a beach ball...

He was rescued by RSPCA inspectors in Cheshire, after he was found wandering around puffed up to twice his normal size.

He was taken to a special vets in Sheffield, where he was diagnosed with 'balloon syndrome'.

It's a very rare condition which can be caused by an injury or infection - meaning the hedgehog puffs up with air under it's skin, like a balloon.

Take a look at him being weighed by the vet.
