Round 2, Question 8 answer
A big orange/brown balloon of thick rubber, with two handles at the top to hold onto, and a little line drawing of a face on the front. I never had one, but friends of mine did. One would sit on top, grab the handles, which were meant to look a bit like ears, and bounce along. This action was so exhausting, though, that no one ever bounced along for more than about fifteen yards. Attempts to go further resulted in fatigue, which led to loss of control, and a fall.
