This stage is set in Pencilvania, featuring the pencil-shaped buildings from the main game's first level. At the start of the level, Alice starts from a higher platform and Samm starts on the ground. Throughout the stage, there are several pits of water, Bumpers, and spikes on the ceiling. There are also several moving platforms which will move down into the water if stood on.
- Internally it is Stage 10 (index number 0x0A), but may appear as Stage L before playing it, if forced on single player mode.
- Although it uses graphics mainly from the first stage of the game, it also incorporates several elements from later stages. For example, Bumpers don't appear in the main game until Sea A (Stage 3) and the only other stage in the main game which uses the ceiling tiles for the floor is the Secret Base (Stage 8). At the end of the level, there are also the loose ground tiles seen in the Northern Sea (Stage 6) but fully white, which isn't seen in any other stage.
