Gigantic Seasick Wreck

Gigantic Seasick Wreck, or , is the sixth level of World Mushroom in Super Mario 3D World. It is unlocked after completing either Trouble in Shadow-Play Alley or Back to Hands-On Hall, and its own completion unlocks Broken Blue Bully Belt. This level is an altered version of Spooky Seasick Wreck, which appears in World 6.

Layout
The level begins on a platform with a Warp Box, which takes the player onto a wrecked ship. The ship has Green Ring which the player must collect to receive the first Green Star, as well as an Octoomba, a moving Ty-foo and a Spike Roller, which moves as the ship rocks. The end of the ship then becomes raised and has another Octoomba and Spiked Roller, which has hidden coins underneath the ship, and a Warp Box.

The next ship contains a 1-Up Mushroom in a hidden block at the front of the ship. The ship contains three Bullies and two Ty-foos, as well as a Mega Mushroom in a Question Block. The ship also goes up, with two Octoombas before another Warp Box. Near the Warp Box is a tilting part of broken ship that has the second Green Star on the end, with an Octoomba before it.

The Warp Box leads to a section of broken ship parts that tilt when walked upon. A Mega Mushroom can be found in a Question Block. Two Ty-foos are located to the left of the tilting platform along with five Octoombas. The third Green Star can be collected above the path near the first Ty-foo. The path eventually leads to another ship, which has another Mega Mushroom in a Question Block, two Ty-foos and eight Bullies which all must be defeated to reveal the Warp Box to progress to the Goal Pole. A hidden block containing a Mega Mushroom can also be found here. The Warp Box leads to the final area with two Octoombas and a tilting platform for the player to reach the top of the Goal Pole with.

This level is an altered version of Spooky Seaside Wreck, and hence has a few differences. The enemies are different, still having Bullies, which are more frequent, but also placing Ty-foos to make travel harder without falling off the ship. Octoombas also frequently appear, and Boos do not appear in the level at all. The layout of the ships are also different, altering the platforms that can be walked on, such as removing a tilting platform and instead using a Warp Box.
