Octopot

The Octopot is a strange jar-like creature that has only appeared in the game Yoshi's Safari. This being lives underwater and is the source of Octos. During the subjugation of Jewelry Land, the Octopot serves as a mini-boss in Bowser's forces.

Mario and Yoshi encounter the Octopot in the fourth level of Light Realm. The creature ambushes the player underwater. The Octopot launches wave after wave of Octos at Mario and Yoshi. Using the Super Scope, the player can blast the Octos right as they emerge from the Octopot, eliminating them. The player can also shoot the Octopot itself. After sustaining gunfire, the jar-like Octopot shatters into many small pieces, thus ceasing to exist. This is the only mini-boss that is not fought twice in the entire game.
