Balloon

Balloons in Poptropica have only several uses.

Handheld balloons
Balloons can be held in your hand.

Can be found at the Clown store at Counterfeit Island and the Poptropica Store.

It is handheld, but not a handheld item. So that means you can both put on your balloon and a handheld item.

Multi-Player Game
The balloon game can be played at any Common Room. The game is like Connect Four, except it's sending the balloon down to up, not up to down. And it has no limit to take turns.
