Piranha Planet

Piranha Planets are pipe balls in Mario & Luigi: Partners in Time, teeming with miniature Piranha Plants equipped with space suits and phasers. They are found 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 right-side up last. Upside down is to Luigi and right-side up is to Mario. It can fall several times on the same target, and each time it is countered with a hammer), it takes damage. They could also shoot lasers at Mario and Luigi. If the Piranha Planet shoots upwards, it either shoots at Mario or shoot from Mario to Luigi. If it shoots upside down, it either shoots Luigi or shoots from Luigi to Mario. If it shoots at one person, it does it multiple times. Its last move is to spawn many Piranha Plants and shoot them at a brother: red for Mario and green for Luigi.
