Lady Lima called Mario and Luigi to the Bean Bean National airport, telling them there is something blocking the path of the plane carrying Princess Peach. The bros. found there were a bunch of Piranha Plants blocking the path along with a large egg.
Every time Mario and Luigi killed a Piranha Plant another one sprouted up. Finally they found that they could beat them all by electrocuting them at the same time, but out of the egg hatched the gigantic Mom Piranha. Mom Piranha was a giant Piranha Plant with tentacles that could grow smaller Piranha Plants.
