This level was one of the four courses featured in demo at E3 2011. Also, the level was based on World 1-1 from the TGS. In the first area, a pair of Binoculars that Mario can use to see Toad near the Flagpole, some Goombas, some dandelions (one of them hides a Super Mushroom; three ? Blocks and a Piranha Plant can be found.) In the next area, there are some Coins and a Venus Fire Trap surrounded by two wood Goombas. The hero must turn to the left to find a Roulette Block and a gap and three moving platforms to go to the other side. If Mario goes to the far left, he will find a small path with three wood Goombas and a real Goomba. In the next area, there is a small mount with some coins. In the right side there is a P-Switch that collects 16 Rainbow Notes and a Warp Pipe. The Checkpoint Flag won't appear in the level. Soon, Mario must go up to the top of a castle. In the way, there are Goombas and Tail Goombas. Three trampoline platforms will send Mario to a Warp Box. It will warp the plumber to a tiny platform floating a bit far from the top of the castle. To reach there, he needs to press a ! panel to make several platforms in the direction of the Flagpole. When Mario lands on the castle, he can use more green reproducing platforms to reach a trampoline to grab the Flagpole's top.
