Meet Dippy, the pensioner penguin

Meet Dippy, he's a Humbolt penguin who needs a bit of extra help getting about.

Dippy is 20 years old, and has a condition called arthritis, which causes pain in his joints.

This means he can't move about as much as he used to.

So keepers at his new home in Great Yarmouth used a special pool with a ramp, to help him move around more easily.
