Malibut

A Malibut is an undersea enemy encountered in Mario & Luigi: Superstar Saga.

Always found alongside Cheep-Cheeps, Mecha-Bloopers and Starkisses, Malibuts attack one of three ways. The first comes in a form of small yellow-green bubbles, which can be jumped over. If the Malibut tilts before attacking, however, it will spit out a large bubble, which must be hit with a Hammer. The last type of attack comes if the Malibut is hit. When struck with any attack, the Malibut will retaliate by throwing one or two pillows at the offender. These pillows must be hammered away to avoid damage.

Trivia

 * The name "Malibut" is a play on the species of fish, "Halibut".
 * It's very likely that Malibuts are relatives of Rip Van Fish.
