Smash attack: Starfishman can jump into the air and perform a downward smash by charging towards the ground with his fist.
Flight: In the DS/GBA version of the game, Starfishman can fly for a limited time.
Hot and cold powers: Usable only in the level "Starfishman to the Rescue," Starfishman can sense where certain mechanisms are, thanks to a radar pointing him in the right direction.
Role in game
Starfishman to the Rescue
Starfishman first appears after Patrick wakes up from a nightmare. He sees a news broadcast saying that the Evil Dreaded Patrick is attacking Bikini Bottom. Patrick soon jumps out from his rock and transforms into Starfishman. He proceeds to go after Dreaded Patrick, all while doing things such as stopping a train from ramming a citizen and finding pieces of his missing clothes. He also goes around the town searching for detergants.
Once he collects all of them, Dreaded Patrick appears and reveals his plan: He is going to launch a citizen starfish into space (he states that the starfish is going to be "The First Fish in Space"). He and Starfishman engage in an elevator duel (which is actually Starfishman fighting Dreaded Patrick's minions while avoiding falling objects). Starfishman wins the duel and goes to rescue the citizen, however, he is not aware that Dreaded Patrick's minions are behind him, who proceed to knock him unconscious.
After he wakes up, he realizes that he is tied to the rocket and blasted into space by his nemesis. However, while he was blasted off into space, he hits a ring-shaped asteroid, which falls into Earth and traps Dreaded Patrick in it.
Continuing from the "Starfishman to the Rescue", Patrick wakes up, still tied to the rocket. After realizing what happened, he flies the rocket through space, while trying to break free from the rope. Throughout his flight, he keeps getting attacked by a Krabby Patty-shaped UFO. He flies through a black hole (filled with gigantic objects like doors and a shovel) and finds a space station on a collision course with asteroids. While inside, he succeeds in untying himself from the rocket and proceeds to man a laser turret to destroy the asteroids, meanwhile avoiding other objects.
After destroying the incoming asteroids, he leaves the station on the rocket again, also being able to use the rocket's laser guns. Starfishman pursues the Krabby Patty UFO, and in a following dogfight, takes it down. He then flies back towards Earth, but cannot stop the rocket from heading down.
Continuing from "Rocket Rodeo," Patrick again wakes up on the rocket, which has plunged into the ocean and is heading straight down towards the rooftops of Bikini Bottom. He then panics and presses a button on the side of the rocket, which stops it, and he gets off. After landing, he finds Mermaid Man on the rooftops and begs him to help him defeat a now-enormous Plankton.
After a series of battles with Giant Plankton and his minions (which involves doing things such as smashing his fingers or calling in the Bikini Bottom Defense Force), Mermaid Man shows Patrick four hidden shrink lasers, which Patrick uses on Plankton to make him small again. A shrunk Plankton falls on top of Patrick, thus ending the battle.
In the final level of the game, "Hypnotic Highway," Starfishman is an unlockable racer. If the player manages to get him, he flies the same rocket that he flew in "Rocket Rodeo" around Hypnotic Highway, against SpongeBob's kart and Plankton's hovercraft.
He is similar to Patrick Man, as they are both superhero alter-egos of Patrick.
The Stafishman seen in Creature from the Krusty Krab was revealed in the end as a part of Dream Patrick's dream which is contained in Gary's dream. However, in Nighty Nightmare, the Starfishman seen is a part of the real Patrick's dream.
