Board notes 5 details

Layout: A pigtail-haired girl makes short bounces over a round orange-and-red trampoline, while a soccer ball sits unused on the grass to the left.
Goal: Store extra tension in the trampoline mat and release it so the girl flies beyond the field into the starry success scene.
Opening: Wait for the girl to return over the center, then press the red mat and drag it straight downward.
Danger Zone: Normal taps produce only low hops, and the soccer ball is irrelevant; the mat must be stretched into a deep pouch before release.
Mechanics: The red trampoline surface can be deformed and released as a catapult, converting a downward drag into an extreme upward launch.
