World 1: Tropical Shores

Tropical Shores is the first world of Super Mario World 3, taking place in a series of small islands that lead up to a shipwreck as the final level. The boss of Tropical Shores is Larry Koopa.
== Levels ==
=== Tropical Shores-1 | Beach Bonanza ===
Tropical Shores begins with Beach Bonanza, a basic beach level.
=== Tropical Shores-2 | Shifting Sands ===
A beach level that revolves around the main gimmick, the lifts. The lifts will sometimes act as the floor as the level, and will shift around, creating sinkholes in the ground that can kill Mario.
=== Tropical Shores-3 | Urchin Underground ===
A cave level that is situated beneath the seas of Tropical Shores. The cavern is populated by buzzy beetles and blurps. Urchins may also lurk in the deeper depths of the underwater tunnel.
=== Tropical Shores-A | Tropicool Coast ===
Tropicool Coast is a frozen beach bonus level that ignores the warmth the rest of the archipelago has. Snow pokeys and blue spike tops roam the frosted sands after evolving due to the extreme cold. There is a secret exit in this level.
=== Tropical Shores-S | Sunken Galleon ===
The final level of Tropical Shores, Sunken Galleon is a shipwreck resurfaced by Larry Koopa, who is also the boss of the level. The level contains fish bones, bullet bills, cannons, and hammer brothers. Larry is fought within an underwater arena while the player is pursued by fish bones.
== Behind the scenes ==
* This world is completely made in Super Mario Maker 2.
* The name "Tropicool Coast" is a pun using the words 'tropical' and 'cool'.
* In the world map, airships and castles will emerge from the water if placed there. This inspired the level "Sunken Galleon".
* The name "Shifting Sands" is a reference to "Shifting Sand Land" from Super Mario 64.
