Sunshine Isles

Sunshine Isles is a special level in Super Mario 64 DS, being accessed in the Rec Room. It is an archipelago of small islands in shallow water, with several trees scattered around the islands. Notably, this level shares it's theme with Delfino Plaza from Super Mario Sunshine.

Geography
There are 6 islands in Sunshine Isles. There are 5 smaller islands, and 1 large island in the center. There are several trees on the islands. There are also 5 Silver Stars scattered throughout the level. The Silver Stars are above trees, in a hidden area behind the large island, held by Klepto, on top of the large island, and on top of a regular island. These Silver Stars unlock the level's only star. Enemies in this level include a Piranha Plant, Goombas, a Lakitu and Klepto.

Super Mario 64 Manifestation
In some personalized copies, Sunshine Isles has been reported to be found in the original Super Mario 64. It usually has a red coin star in place of a Silver Star star, though if Silver Stars are also in that copy, there may also be a Silver Star star.
