World 13-3 (Super Mario Maker for Nintendo 3DS)
From the Super Mario Wiki
World 13-3 is the third level of World 13 of Super Mario Challenge from Super Mario Maker for Nintendo 3DS.
The course starts off with a small piece of an airship and a Flimsy Lift on a track going down diagonally. Below this is another small part of an airship with a Hidden Block containing a Super Mushroom on a Super Leaf. Grinders are on all of the edges of the airships except the one near the beginning. Donut Blocks separate the airships. Designs and sails of the ship are made of Semisolid Platforms and only the latter has yellow Mushroom Platforms. The first has a Hidden Block with a 1-Up Mushroom above the top part of the airship. The Airships get longer as the player progresses through the level. Enemies (mainly Dry Bones) patrol the airships, with only some not reachable. The last and longest airship has two secret areas of the ship that can be assessed. Above the longest airship are winged coins and one winged 1-Up Mushroom. At the end of the longest airship is a Big Parabones with a Big Spiny on top. If the player gets close enough, a Monty Mole will come out of the ground and chase the player. After this, a Flimsy Lift going diagonally up will take the player to the Giant Gate.
