Wear one of the eight silly hats and complete the challenge, from playing ping pong on your head to hoopla with someone wearing a cone hat.

Lose your head in a Deeley Bopper battle or carefully try not to spill water from your top hat. But watch out, you don’t want to be wearing the bowler hat when the balloon goes with a bang…or sloshes you with water!

Comes with ten water balloons, water bottle, hoopla rings and a sense of foreboding that it will be you who gets wet. Make your party go with a bang!
