Red Electrokoopas are variants of the Koopa Troopa that appear only in Super Mario Sunshine. Red Electrokoopas are one of two kinds of Electro-Koopas, along with blue version. Both are quadrupeds and have electrical shells. Red Electrokoopas are mostly found in Pinna Park and Pianta Village; more specifically, they appear in Pinna Park in Episode 3 (Red Coins of the Pirate Ships) and Episode 5 (The Runaway Ferris Wheel), and in Pianta Village in Episode 3 (The Goopy Inferno), where they climb on metal fences. The Huge Red Electrokoopa (which is colored green) causes the problem in The Runaway Ferris Wheel.
To defeat Red Electrokoopas, Mario must kick, punch, or Ground Pound them from the other side of the fence or below them. When this happens, they fly off. They will shock Mario if he touches them, although they damage Mario by the shock and not by knocking him out of the metal fence, unlike a Klamber. Also unlike Klambers, Red Electrokoopas merely crawl back and forth, instead of following Mario. As they climb, a squeaking noise can be heard; it is unknown if they produce the noise or if it is merely the grating they are walking upon creaking.
Red Electrokoopas are found at the following locations:
