World 4 is the fourth of the seven worlds in the game Super Mario Bros. 2/Doki Doki Panic. The world has a unique snow and ice theme to it, and introduces the player to the Flurry and Autobomb enemies. The boss of this world is Fryguy, who is an intentionally out-of-place boss for this world, being a fire creature in an ice-covered world.
Areas[ | ]
World 4-1[ | ]
The first part of the level consists of dodging Flurries while sliding on icy surfaces and jumping over pits. At the far right there is a plant that turns into a rocket ship when pulled up, which takes the player to the next part of the level. Level 4-1 is notable for being the only level in the entire game without a boss, instead it hasa long area filled with many enemies, with the boss music playing in the background. The crystal ball is lying unguarded on the ground at the end.
World 4-2[ | ]
World 4-2 can be noted for being the only level in the game that has whales in it. The level starts underground, and has a vine that you climb to the first main part of the level. Then slide, duck, and jump along the ice while dodging a flock of Beezos. After going through a doorway, the next section has the whales in it. The water coming through the blowholes can hurt the player if the player hits it from the sides, but the player can stand on top of it.
This level also has a hidden warp to World 6. After the player enters the area with the whales, look for a magic potion. Carry it forward until there is a vase. Enter the vase after crossing over to the dream world, and the player will warp to World 6.
World 4-3[ | ]
In world 4-3, a Birdo is strangely seen as a seemingly normal enemy early in level, and reappears after being defeated whenever the player reenters the room it is in. This allows it to be defeated an infinite number of times for a massive amount of points. The actual purpose of this out-of-place Birdo is for the player to ride on one of its eggs across the otherwise impassable ocean to reach the main dungeon where Fry Guy's lair is located.
