Shuri

Shuries are starfish enemies that first appear in Donkey Kong Country 2: Diddy's Kong Quest. They appear in the underwater areas of Donkey Kong Island and Crocodile Isle. Their name is derived from shuriken, a spinning weapon which incidentally resembles a starfish. Shuries are shaped like a shuriken, and they spin like one while moving around.

Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest, Shuries appear in many underwater levels, starting with Lockjaw's Locker. There are two color variants, orange and pink, and they have slightly distinctive behavior. The orange Shuries spin through the water in diagonal lines and bounce off the walls. The pink Shuries await Diddy and Dixie Kong in a corner, and when the Kongs approach a Pink Shuri, it spins in their direction. Like other enemies, if the lead Kong gets hit by a Shuri, they take damage. Like most aquatic foes, Shuries can only be defeated by Enguarde the Swordfish.

In the ending's Cast of Characters, Shuries appear under the Submerged Seadogs category.

Donkey Kong Land 2
Shuries also appear in Donkey Kong Land 2. Because of the Game Boy's monochromatic palette, their color variants are not present. Shuries can only move in straight lines.

Donkey Kong 64
Shuries make another appearance in Donkey Kong 64. They are uncommon enemies who are only encountered in a few underwater areas. Shuries are larger than in their previous appearances. Only the orange Shuries reappear, and they were made slightly larger. The Shuries retain their attack patterns from Donkey Kong Country 2: Diddy's Kong Quest. Unlike their previous appearances, Shuries cannot be defeated.

The game introduces a purple variant of Shuri in scuba gear, named Scubi.

DK: King of Swing / DK: Jungle Climber
Shuries also appear in DK: King of Swing and its sequel DK: Jungle Climber. In both games, they retain their attack pattern, and can be defeated from a charge attack.

Super Mario-kun
A Shuri makes a brief cameo in Volume 14 of Super Mario-Kun. The last part of the book has a series of comics based on Donkey Kong Country 2: Diddy's Kong Quest, including a 'find the differences' activity between several enemies, including Shuri.
