It's Balloon-Headed Boy's Birthday, and the King of the Balloons has arranged a huge party for him at Balloon Castle. All of the balloons in Balloon Town have been invited and everyone is very excited.

However! The night before the party, there is a terrible and sinister storm. Magical winds rip through Balloon Town, scattering the inhabitants throughout the land. And worse! It rains frogs - each one hopping mad, and quite intent on popping all inflated lifeforms they find!

Help Balloon-Headed Boy race through multiple levels of rubberised madness - collect farty flowers to inflate his head and soar between the platforms, thwop those frogs, keep your head above the rising waters, and rescue the balloons so the birthday party can go ahead as intended!
