Super Mario series
Super Mario 64
The first known Dorrie from Super Mario 64 lives in an underground lake in the Hazy Maze Cave. He spends his days swimming in circles, but will gladly give Mario a ride if he gets on his back. It is also possible to steer Dorrie by carefully climbing up onto his head; Mario will lose control of movement for a moment, then the player can control Dorrie by facing the direction they want to go in. Ground Pounding on his back or approaching his neck will cause him to lower his neck, making this task easier. A sign near the lake in which he takes residence states that he might eat visitors if they get too close, but he is actually a harmless creature.
Super Mario 64 DS
Dorrie also appears in Super Mario 64 DS. He now wears goggles, and resembles the Dolphins in Super Mario World. He fulfills the same role as in Super Mario 64, giving the player a ride wherever he wants to go. When Wario is unlocked, Dorrie sometimes has Wario's Cap on his head (unless the player is playing as Wario). The same sign warning the player to not become Dorrie's lunch reappears, but once again, Dorrie himself does not eat any visitors.
New Super Mario Bros.
Dorrie returns in New Super Mario Bros., using his Super Mario 64 DS appearance, and appears in two sizes. Mario can ride on his back to cross large bodies of toxic water in World 4-1 and World 4-6. If Mario does a Ground Pound on Dorrie, he will move faster through the water.
Mario Party series
Dorrie is a recurring minor character in the Mario Party series. Although only directly appearing in a few games, such as Mario Party 3 and Mario Party Advance, a lot of aquatic equipment in the Mario Party series, such as boats, are based on Dorrie.
