Guppy

"What, you again? You got to be kidding me! You want to run me out of this lake? You got to get through all eight rings!"

- Guppy

Guppy is a minor character in Super Mario Galaxy. He is an orca who appears in a few of the game's missions. In two of the missions, he "takes over" a large body of water, and if Mario wishes to take it back, he has to swim through eight rings in a set amount of time. After Mario does that, Guppy rewards him with a Power Star. Guppy also appears in the Sea Slide Galaxy, Deep Dark Galaxy, and in the moat of Peach's Castle in the Mushroom Kingdom at the end of the game.

If Mario touches Guppy, Mario bounces back on the ground and lose a Shell if he is holding one, but he will not take damage.

Guppy is suspected to be connected to a terrorist organization. The evidence supporting this is the fact that you cannot jump on him as you can nearly every other NPC in the game.

Super Mario Galaxy trading card description
''Guppy's bark is definitely worse than his bite. This orca may look menacing, but he's really only aggressive to penguins and Toads. To Mario, Guppy is ultimately harmless, but he does present two challenges: he'll make Mario swim through eight rings in one body of water, and if Mario bumps into him, Guppy will bounce him to the floor. Look for Guppy in the Sea Slide Galaxy and the Deep Dark Galaxy.''

Trivia

 * According to the Prima guide for Super Mario Galaxy, Guppy was originally going to be a generic dolphin and a friendly character, despite him already being one, as orcas are a type of dolphin.
 * The Prima guide also incorrectly referred to Guppy as a shark.
 * In the German version of the game, Guppy refers to himself as a shark instead of an orca.
 * In the Deep Dark Galaxy, Guppy will still act as if he has met Mario even if he has not been encountered in the Sea Slide Galaxy yet.
 * The Prima guides claims that Guppy is only aggressive to penguins and Toads. This may be a reference to how orcas are natural predators to penguins.
