World 5 (New Super Mario Bros. Wii)

World 5 (also known as the Jungle World ) is the fifth world in New Super Mario Bros. Wii. The world is a tropical rainforest with poison, which can be seen in some levels. Bramble vines block some of the paths, and will usually change positions after Mario clears or fails a level. There are eight levels in this world, including a tower and castle that are guarded by Iggy Koopa, and a Ghost House. It also has a total of nine exits. There is also a Warp Cannon that sends the player to World 8.

This world features one Toad House of every color; red, green, and yellow. On the map, there are three Stalking Piranha Plants that act as the world's Enemy Course; this is the most that occur in any of the game's worlds. Once Iggy is defeated in the castle, the bramble patches disappear completely.
