Dorrie

Dorrie (also known as Swimming Beast) is a large, friendly swimming blue -like sea dragon who debuted in Super Mario 64. He helps Mario, Luigi, Wario, and Yoshi ride across water or reach higher areas. Super Mario Odyssey explicitly refers to Dorries as a species and it features two additional Dorries, one purple, and one yellow. In terms of design, Dorrie has a few elements in common with Yoshis, such as the white area of soft tissue spanning the whole lower part of the body and a similar round face that, since Super Mario 64 DS, even features a placement of the eyes and nostrils akin to that seen in Yoshis. Furthermore, the two species share the suffix, -sshi (「ッシー」), in their Japanese names.

Super Mario 64 / Super Mario 64 DS
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 from there; 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, allowing Mario to climb onto his head to reach higher areas, like the entrance to the Cavern of the Metal Cap. 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.

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, 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 Poisoned Water in World 4-1 and World 4-6. If Mario does a Ground Pound on Dorrie, he will move faster through the water.

Super Mario Odyssey
Dorrie appears in Super Mario Odyssey, where it can be seen wearing a top hat and swimming in the Lake Kingdom and the Mushroom Kingdom. Purple and yellow-colored Dorries also appear in the Seaside Kingdom, where they wear hats and are associated with the Crazy Cap shop. In this game, genderless pronouns are used to refer to Dorrie. This game depicts Dorries as speaking in long-held moaning noises, such as "AoouuuooOOooOooOoo," which are subtitled in parentheses. A Rubber Dorrie can be purchased from the Lake Kingdom's Crazy Cap shop as a souvenir for the Odyssey. Dorrie also appears at the beginning of the Darker Side.

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.

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 5
In Mario Party 5, red, blue, green, and yellow plastic Dorries appear in the minigame Tug-o-Dorrie.

Mario Party Advance
In Mario Party Advance, Dorrie resides at Loch Dorrie, and reveals that he is lonely after scaring away Mr. E. If Yoshi visits him, they will become friends and Dorrie gives him a Gaddget, the Soil Sonar. However, the credits state that Yoshi has not seen him in ages. Despite Mario Party Advance having been released after Super Mario 64 DS, Dorrie uses his original design instead of his updated design.

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 Nessi. Also, the English name of his location in Mario Party Advance, Loch Dorrie, is a reference to, the supposed home of the Loch Ness Monster.
 * Dorrie shares his Japanese name with Bahamutt.
