Giant Clam

Colossal Clambo is a large Clambo boss encountered in the last area of Kremlantis, Seabed Showdown, in the game Donkey Kong Land. Unlike its unmoving brethren, the Colossal Clambo is perfectly capable of moving through the water.

The Colossal Clambo can attack Donkey or Diddy Kong by moving around and spitting pearls at them. He has a simple attack pattern, however, as he shoots the pearls from the opposite corner that the Kongs are in. In order to harm the giant boss, the Kongs must trick it into shooting its pearls at another nearby smaller Clambo, then quickly move out of the way before the pearl hits them. The pearls then bounce off this enemy and smash into the Colossal Clambo. After being hit several times, the Colossal Clambo begins to move faster and shoot pearls at a quicker pace. Despite this, Colossal Clambo can be defeated after a few more hits.
