Kani Pearl

Kani Pearl is the second boss in Sonic Labyrinth. Kani Pearl awaits Sonic at the bottom of a long, ring-filled slope in Act 4 of Labyrinth of the Sea.&nbsp The boss arena here is a sloping E-shape. Sonic is first beset by waves of miniature crab badniks crawling down the inclines, but they are easy enough to avoid simply by spin dashing. When Kani Pearl finally materializes, the mechanical crustacean simply scuttles sideways back and forth along the upper level. Impervious to damage while its shell is closed, the boss should be attacked when it flips open its armor to fire a pearly bullet in Sonic's direction. 5 hits destroy it, and Sonic can grab the Chaos Emerald.

Name Origin
The word "Kani" means "crab" in Japanese. Since Kani Pearl is a crab, this may have been where the name originated from.
