Game:Flotsam and Jetsam

Flotsam and Jetsam are bosses from Kingdom Hearts that appear in Atlantica. They fight as a pair, aiding Ursula in her first form.

Kingdom Hearts
Flotsam and Jetsam swim around Ursula's lair, attacking by biting periodically. Sora must focus on casting spells onto Ursula's cauldron. The main spells to use are Fire, Blizzard, and Thunder—the best of them is Fire, as it consumes little MP and it is the first on the Magic menu. Flotsam and Jetsam revive periodically after being knocked out, so be sure to keep them at bay. Allow your party members, preferably Ariel and Goofy to take care of them while you focus on Ursula. Or, if they are still posing a threat, Sora can take them out himself, but should do so at a safe distance from Ursula.

Kingdom Hearts II
In Ursula's Revenge, Flotsam and Jetsam briefly appear, but both are destroyed by Magic from Sora's Keyblade.
