Flooded Forest
The fourth forest themed world in Super PaulCif World, found east of Dry Desert Hills and south of Powdery Snow Peak. This is the first world to introduce split paths, where players only need to complete one level in that split to progress. There are five levels here: four normal levels and a castle. Iggy Koopa is the world boss at the sunken fortress.
Shoe Goomba Grotto
The first forest level that focuses on the Shoe Goomba as the main power-up and enemy. When wearing the Winged Shoe, players can hover in the air by holding the jump button. If the hover has already been used, it refreshes after stomping on an enemy.
Poison Snake Lake
One of two forest night levels where players must ride Fast Snake Blocks to progress. After the first checkpoint, the poison continuously rises in the second vertical part of the level. Unlike regular Cheep Cheeps, their poison variants cannot be stomped on.
Poison Poltergeist Pond
One of two forest night levels filled with Boos, Dry Bones and poison that periodically shifts up and down. The Dry Bones Shell is the main power-up that can safely surf on poison and stomp on Boos. Additionally, the Dry Bones Shell can perform a ground pound midair to pass through Rotating Blocks and become temporarily invulnerable by turning into a pile of bones by pressing down on the analog stick or d-pad.
Persistent Prickly Pests
A level filled with Piranha Creepers, Porcupuffers and water that periodically shifts up and down. Porcupuffers actively chase players throughout the level in an attempt to eat them until they are defeated. It takes four consecutive fireballs from a player’s Fire Form to puff up and burst a Porcupuffer.
Sunken Fortress
The second and final level that is entirely underwater and the fourth castle level. In addition to Cannons, the fortress is also armed with Bill Blasters that fire Cheep Cheeps instead of Bullet Bills. Iggy Koopa is fought at the end.
