[[File:Spp1.jpg|thumb|left|Peach battling Boss Piranha Plant in ''Super Princess Peach''.]]
In ''[[Super Princess Peach]]'', he is named '''Boss PiranhaP. Plant''' (short for '''Boss Piranha Plant'''), and is named Petey Piranha in Britishthe EnglishEuropean releases)version. Boss P. Plant is the first boss, and he is fought at the end of [[Ladida Plains]]. When Peach arrives she happily approaches an imprisoned Toad but then, Boss Piranha Plant emerges from the ground and swallows the Toad, who is trapped in the ball, and Peach has to defeat Boss Piranha Plant to rescue the Toad. His attacks send shockwaves, pushing back Peach, shooting [[Nipper Plant]]s, shooting one shockwave to the left and one to the right (which can defeat Nipper Plants if there are any not defeated by the princess), and if she is using a vibe power, ending it. Peach has to use her [[Gloom]] vibe to make the two plants grow so that she can leap on a leaf and once again use the vibe to put her streams of tear into Boss Piranha Plant and inflate him, making him fall and reveal his weak spot: his belly button. Peach has to jump on his belly five times to defeat him. After 3 hits, Boss Piranha Plant turns red and becomes faster. Boss Piranha Plant can also bounce around at this point, making Peach's attack tough, and additionally send 2 shockwaves to each side. Once defeated, Boss Piranha Plant explodes and the Toad is saved.
