Timmy's Bouncy Friend - S3.E20

Timmy's new friend is big, round, friendly and very, very bouncy. It's a space hopper. Timmy tries to involve his new pal in his nursery day but it is very awkward and keeps causing accidents. It's only when Harriet confiscates the space hopper that Timmy works out what it's really for: loads of bouncy fun!
