Piranha Planet

Piranha Planets are small Pipe Worlds teeming with miniature Piranha Plants equipped with space suits and phasers in Mario & Luigi: Partners in Time. The four Mario Bros. encountered many of these strange planets during their adventure in the Star Shrine. They can harm the brothers by several ways. One way is to try to fall on one of the heroes. This can be predetermined by if it was upside down last or rightside up last. Upside down is to Luigi and rightside up is to Mario. It can fall several times on the same target, and each time it is countered (with a Hammer), it will take damage. They could also shoot lasers at the heros. If the Piranha Planet shoots upwards, it'll either shoot just Mario, or shoot from Mario to Luigi. If it shoots upside down, it will either shoot Luigi or shoot from Luigi to Mario. If it just shoots one person it'll do it multiple times. Its last move is to spawn many Piranha Plants and will shoot them at a brother; Red for Mario and Green for Luigi.
