World 5 (New Super Mario Bros.)

World 5 is the fifth world in New Super Mario Bros.. This world is unlocked by four methods; by taking the respective Warp Cannons of Worlds 1 or World 2, or by completing the Castle levels of either World 3 or World 4.
== Layout ==
The world is set in a snowy plain filled with icy mountains and ground, similar to Ice Land from Super Mario Bros. 3. The boss of this world is Petey Piranha, who has to be defeated by ground-pounding on him three times, allowing access to World 6, though if the player completes the castle in mini form, they will gain access to World 7 instead.
This world features 3 mushroom houses, and a cannon, which leads to World 8. This world also features 2 Warp Pipes, which connect World 5-2 to World 5-3, and World 5-B to .
Starting with this world, in reference to Super Mario Bros. 3, Hammer Bros can be found on the overworld amongside the flying red ? Blocks, and if Mario/Luigi enters a course with the Hammer Bro on it, they can defeat the Hammer Bro to get any power-up, except the Starman. And just like the flying red ? Block, Hammer Bros will avoid going to Castles.

== Trivia ==
* World 5 seems to be the snow/ice counterpart to World 2.
** Both worlds feature Warp Pipes in the overworld to take Mario/Luigi to other levels.
** The towers and castle levels include environments of the world's theming in some way.
** To unlock secret worlds (Worlds 4 and 7 respectively) Mario/Luigi have to defeat the respective bosses of the castles with the Mini Mushroom power-up.
** To access the castle, it can either be taken through a Warp Pipe via a secret level World 2-A and World 5-B) or complete an auto-scrolling level before the castle (World 2-6 and World 5-4).
** Elements from World 2 reappear in World 5, such as blocks that extend three times vertically (found in both World 2-1 and World 5-1), Swoopers (in World 2-3 and World 5-2), Hammer Bros (in World 2-4 and any level of World 5 besides the castle), and Spiked Balls ( and ).
** Both worlds can unlock three other worlds by beating the castle normally, with Mini form, or by Warp Cannons respectively (World 2 can unlock Worlds 3, 4, and 5, and World 5 can unlock Worlds 6, 7, and 8).
* World 5 also shares some similarities to World 3 in terms of overworld layout. 
** Both worlds feature 2 normal levels and an unlockable secret level before the tower level, but unlike in World 3, the first level of World 5 has to be done to play any other level in the world.
** Both towers can be skipped via secret exits in the second normal levels (World 3-2 and World 5-2).
** Both worlds have three secret levels, and upon completing the second secret levels (World 3-B and World 5-B) can unlock the third secret levels (World 3-C and World 5-C. Both secret levels can also be used as an alternative path to the castle levels, and skipping the world's Ghost Houses.
** Both overworlds also feature one of each type of Mushroom Houses.
