World 5 (Super Mario Bros. 2)

World 5 is the fifth world in Super Mario Bros. 2, and all subsequent remakes, most notably Super Mario Advance. Like World 1 and World 3, it has a traditional grass-type theme, although some of World 5 takes place at night. This world introduces Birdo's green form, the hardest form of Birdo in the game because she fires only fireballs and must be defeated using other projectiles. In the original Doki Doki Panic, the boss was a repeat of Mouser, but for the SMB2 version, he was replaced with a new boss, Clawgrip the crab.

World 5-2
This level tests the player's precision jumping as they cross a huge waterfall while jumping on logs, fish, and a few pieces of land.

World 5-3
This level has a hidden warp to World 7 that can only be reached if the player plays with Luigi, because he can jump the highest. Near the start of the level, right after climbing up the later, there will be a platform above Luigi's head. He must Super Jump up on top of it, and find the magic potion. After entering dream world, he needs to enter the vase and will be warped to World 7.

This level features more Autobombs than any other level.
