1-2 (NSMB)

World 1-2 is a level in New Super Mario Bros.. It is the level that is right after level 1-1. It is almost a complete remake of level 1-2 from Super Mario Bros.

Overview
Pursuing the chase after Bowser Jr., Mario finds himself in a strange cave. Adventuring on, Mario finds that many Goombas and Koopa Troopas inhabit this cave. He then sees some blocks. Hitting it produces Coins. Mario collects them, and moves on to a strange sight - a Star Coin. He jumps onto the ledge, and collects it, he then moves on, encountering more Goombas. Going forward, Mario finds a block of rock that he can't get through - yet he prevailes by smashing the blocks above it, and getting through. A hole is then met, Mario easily jumps over it, but then meets a Star Coin embedded in some blocks. Trying to find out how to get in, Mario jumps to the top and accidentally ground pounds it - the blocks then go in, creating a passgeway to get the Star Coin. A Piranha Plant is then met. Mario jumps over it, and goes down the pipe it was guarding. Mario, finding a passageway, collects the Coins, then hits the Koopa Troopa, creating a passage way to be created by the Koopa Troopa's shell. Mario waits until its done, and crawls udner the passageway - he then comes accross, and is greeted by some Goombas. Running, he then meets a block. A Mega Mushroom pops out. Mario collects it, and destroys all the Goombas. He then goes up a pipe nearby. Mario is then in the cave again, and jumps carefully over some pipes sticking out of a hole. He then makes it onto the ground, and runs forward. He then meets a strange log. He runs over it, and continues through the cave. A pipe then greets him, as he appears out of the pipe, and into the sunshine again, and also near the Flagpole. He then finishes the level.
