Locked in the game until the expansion is purchased. Then chapters 6–20 open, with all 150 of their levels.

Goal: Light the lamp, then ring the bell, then get both tennis balls into the basket.

Two glass tanks stand at the bottom. A tennis ball waits on a shelf by a bell, another sits in the left tank, and the basket shares a ledge with a lamp. Light the lamp, ring the bell, then get both balls into the basket.
