Piscatory Pete

Piscatory Pete are a faster golden subspecies of Rip Van Fish that appear in Yoshi's Island DS. They are much more aggressive than Rip Van Fish and actually chase you upon seeing you. Only one Piscatory Pete appears in the entire game near the end of the Submarine section in 3-3 however despite this, multiple Piscatory Petes appear in the Museum alongside some Rip Van Fish. Rip Van Fish in Super Mario World behave in the exact same way as Piscatory Petes the only difference being is they're asleep until you approach them while these guys are just moving left to right until you approach them.
