Dorrie

Dorrie is a large, friendly plesiosaur that debuted in Super Mario 64. He helps Mario, Luigi, Wario, and Yoshi ride across water or reach higher areas.

Super Mario 64
Dorrie makes his debut in Super Mario 64, where he 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, although he is actually harmless.

Super Mario 64 DS
Dorrie reappears in Super Mario 64 DS with an updated design, with the most noticeable change being a pair of goggles that are highly similar to the ones worn by the Dolphins in Super Mario World. He reprises his role as in Super Mario 64 by giving the player a ride wherever they want to go. Dorrie wears Wario's Cap only during the first mission of Hazy Maze Cave even before Wario is rescued, unless the player is playing as Wario himself.

New Super Mario Bros.
Dorrie returns in New Super Mario Bros. 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.

Mario Party 2
In Mario Party 2, Dorrie makes a small cameo in Mystery Land in the background lake, with his appearance resembling the photograph of the Loch Ness Monster.

Mario Party 3
In Mario Party 3, Dorrie is seen in an Item Minigame called Dorrie Dip. He also makes a cameo in the background of the board Creepy Cavern.

Mario Party 4
In Mario Party 4, Dorrie is seen as a paddle boat in the minigame Right Oar Left?

Mario Party Advance
In Mario Party Advance, Dorrie reveals that he is lonely after scaring away Mr. E. If Yoshi comes, they will become friends and Dorrie gives him a Gaddget, the Soil Sonar. The credits show that Yoshi ought to visit him soon. It says that he has not seen him in a while, or as it says, ages. Despite Mario Party Advance having been released after Super Mario 64 DS, Dorrie uses his original design instead of his updated design.

Mario Party 5
In Mario Party 5, plastic Dorries appear in the minigame Tug-o-Dorrie.

Trivia

 * In the Japanese version of Super Mario 64, Dorrie is referred to as "Doshi", most likely as a parody of the Loch Ness Monster (who is commonly referred to by the nickname Nessie, which is pronounced "Neshi" in Japanese) and Yoshi. In the German version of the game, he is actually called Nessie. Also, the English version of where his location in Mario Party Advance, Loch Dorrie, is a reference to Loch Ness, Scotland, the supposed home of the Loch Ness Monster.
 * Although Dorrie is referred to with male pronouns in his first appearance, Mario Party 3 uses female pronouns in some minigames.
 * Dorrie shares its Japanese name with Bahamutt.
