Sea Lion only appeared in The Holiday. Kipper was playing with his ball in the water when he dropped it, it moved away and the seal was moving the ball and played catch with him. Later, when Tiger goes for a wash in the sea, then he sees the seal playing with the ball and tells Kipper to come quick, but Kipper's busy reading Tiger's book. The seal comes by and knocks over the beach chair. Tiger and Kipper laugh together and then go for a swim in the water with the seal.
