Attacks
 * Megaton Hydro Laser: Channels ultra-high speed water currents through its mouth-cannons.
 * Jumbo Crater: Simultaneously strafes with all of its beam cannons so that it covers 360°, leaving behind a crater. This technique embodies the saying, "Offense is the best Defense."
 * Jumbo Jetter: Retracts its legs and fires both of its arm-cannons behind it, accelerating it into a spinning charge at the opponent.
