Sunshine Seaside

Sunshine Seaside, numbered World 5-1, is the first course in World 5 from Super Mario 3D World. The level is unlocked by either clearing Lava Rock Lair in World 4, or entering the secret Warp Pipe in Piranha Creeper Creek.

Layout
The first and main area of this level is a sandy beach. Here, Mario will find palm trees, sand statues and five Key Coins. There are also Koopa Troopas and a team of Chargin' Chucks. The so-called "sea" ends at a bottomless pit.

The Key Coins open the Warp Box to the next area, a floating island with the Checkpoint Flag and a Warp Pipe. The player is sent to a cavern where they ride Plessie through a river, dealing with Splounders and moving bridges along the way. Another Warp Pipe at the end of the cave takes Mario to the final island, where the Goal Pole and some Para-Biddybuds are found.

Green Stars

 * Green Star 1: Inside a Goomba sand statue near the start of the level.
 * Green Star 2: A secret room can be accessed via a Warp Pipe in a hole under the water, next to the first Warp Box. Inside it, Mario must step on every panel on the ground to reveal the Green Star.
 * Green Star 3: There is a small cave in the wall to the very right of the first section. If the player defeats every Biddybud there, Captain Toad gives them the final Green Star.
