World 1-2 (Super Mario Bros. 3)

World 1-2 is the second level of Grass Land in Super Mario Bros. 3 and the second overall in the game. This level takes place in a grassy area with many hills and also some pipes that stick out of the ground, where Note Blocks first appear. but are not able to be entered. Mainly Goombas and Venus Fire Traps inhabit the area. A variation of a Paragoomba that produces Micro Goombas can be found at the end of the stage. Mario can make use of a P-Switch or a Super Leaf to gain access to a floating Warp Pipe located halfway the level. This will earn the player 20 coins. One of the many Jump Blocks in that area also contains a Starman.

By utilizing the second Goomba-hatching pipe in the level, and using Raccoon Mario's tail-gliding to jump from Goomba to Goomba, Mario can rack up an extraordinary number of lives. Between using this trick and collecting the 1-Up above the pipe midway through the level, it is not unreasonable for Mario to complete the level with a total of 30 lives or more.
