The Rhino Cannon resembles a Rhino Jet with a cannon mounted on top.
The Rhino Cannon stays in place, and fires bombs at the player should they approach. Upon its destruction, it awards the player one hundred points. Its bombs are of the same type and appearance of those of the Kikis', and can also be picked up and thrown.
The Rhino Cannon is generally a weak enemy, and its behavior mostly remains the same in both Normal and Hard Mode. They only appear in the normal mode of Dry Lagoon, and the normal and Hard Modes of Pumpkin Hill.
