Board notes 5 details

Layout: Jenny hangs sideways from a horizontal line near a blue kettlebell; a small red balloon is at the left, a white bird is on the right, and a spring and a pair of wings sit below as decoys.
Goal: Inflate the red balloon with Jenny's mouth, then use the inflated balloon to pull her legs upward into a handstand.
Opening: Drag the red balloon from the left side of the line to Jenny's mouth.
Danger Zone: Tapping Jenny's body or using the kettlebell, spring, wings, or bird does not make her balance; the balloon must first touch her mouth.
Mechanics: The balloon changes from a small red object into a large inflated balloon at Jenny's mouth, then remains draggable and lifts her when attached to her feet.
