Mom Piranha

Mom Piranha is a giant Piranha Plant that took up residence in a large egg on the runway at the Beanbean International Airport during the events of Mario & Luigi: Superstar Saga. She sent her offspring to take root in the runway, preventing planes from landing or taking off. Thus Princess Peach, who had an important meeting with Queen Bean and Prince Peasley, was unable to land her plane. However, Mario and Luigi develop a clever plan to clear the runway. Mario would drink water and spit it on the Piranha offspring, soaking it and making it swell up and turn a dull turquoise color. Luigi would then shock the unfortunate plant with electricity. Since the offspring were connected to Mom Piranha, the electricity would surge through the roots of the Piranha Plants and into her egg, causing it to crack open, one bit at a time. In the end, Mario and Luigi ended up defeating Mom Piranha in battle, allowing Peach to safely land her plane.

Mom Piranha had several offensive abilities, such as slapping the Mario Bros with her tentacle-like arms and spitting a large ball of energy at the Marios. However, Mario and Luigi had more trouble with Mom Piranha's Piranha Plant minions and her extremely high defense. There were usually two Piranha Plants with Mom, varying in color from red to blue. Mom Piranha's color would be whatever the majority of the Piranha's colors were (starting at red with two red plants). If the Piranha Plants were different colors, Mom Piranha would not change color, unless the other plant of her color was defeated, and one of the opposite color appeared. Mom Piranha could also raise another Piranha Plant if one was struck down but sometimes doesn't. In addition, for every plant of her color, Mom Piranha would regain ten health points at the end of each turn. Most attacks on Mom Piranha would do minimal damage. However, Mario and Luigi could deal a large amount of damage by using Thunderhand and Firebrand when Mom Piranha was red and blue, respectively. Unfortunately, this would cause all of the Piranha Plants to react and spit out fireballs and electricity in a random, frenzied manner.

Trivia

 * Mom Piranha is like Megasmilax and Lava Piranha from previous Mario RPGs.
 * Strangly, in the US version of the game if the Mom Piranha was defeated when she was blue, she would give out no coins.
