After years of experimental testing the animals have devised a plan to escape! Using the distraction of a nearby festival each creature will use bunches of balloons to float to safety. Unfortunately the evil Doctor has caught wind of the plan. He has despatched his army of lab rats to destroy the festival balloons and force the escapees back to earth. Help each of the animals float to freedom by dragging balloons over to increase their lift. Be aware each animal can only afford a certain number of balloons.
