Sunshine Seaside

Sunshine Seaside, otherwise known as World 5-1, is the first course in World 5 from Super Mario 3D World and its Nintendo Switch port Super Mario 3D World + Bowser's Fury. The level is unlocked by either clearing Lava Rock Lair in World 4, or entering the secret Warp Pipe in Piranha Creeper Creek. Completion of this level unlocks both Tricky Trapeze Theater and Backstreet Bustle.

Layout
The first and main area of this level is a sandy beach. Here, players find palm trees, sand statues and five Key Coins. There are also Koopa Troopas, Biddybuds, Mini Goombas hidden within a Goomba statue, 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. Players are 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 the players to the final island, where the Goal Pole, a lone Koopa Troopa, and some Para-Biddybuds are found.

Green Stars

 * Green Star 1: Inside the rightmost of the three Goomba sand statues 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, players must step on every Color 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 players defeat every Biddybud there, Captain Toad gives them the final Green Star.

Stamp

 * Above a wooden platform during Plessie's section. It depicts Beach Koopa's Super Mario World artwork.

Luigi sightings
In the beginning area, the player can use a Sprixie's binoculars to see an 8-bit Luigi up in a tree. Also, if the player torches one of the bushes after the Plessie ride, another 8-bit Luigi can be seen.
