Plessie is a friendly character resembling a nothosaur (yet referred to as a "dinosaur" by Nintendo) that debuted in Super Mario 3D World. In the game, it allows the playable characters to ride it through certain levels, similarly to Dorrie in Super Mario 64 / Super Mario 64 DS and New Super Mario Bros. Plessie's name is a portmanteau of "plesiosaur" and "Nessie." The former is an extinct group of large marine reptiles that are often confused as dinosaurs, whereas the latter is the nickname given to the Loch Ness Monster. Its design shares some features with the design of Yoshis, such as the bipedal posture with short legs, the white soft tissue that spans the lower part of the body, big oval eyes pointing forward which feature a white sclera, the nostrils being hosted near the top of a round protruding end of the upper part of the muzzle, and a crest on the back of the head, although the shape of the latter is different. They also share the same suffix, -sshi (「ッシー」), in their Japanese names.


Super Mario 3D World / Super Mario 3D World + Bowser's Fury[edit]

Plessie in Super Mario 3D World.

In Super Mario 3D World and its Nintendo Switch port, Plessie first appears in World 1-4, Plessie's Plunging Falls, where Mario and company must ride it through a river to reach the Goal Pole. It also appears in World 5-1, Sunshine Seaside; World BowserWorld Bowser icon from Super Mario 3D World.-2, Plessie's Dune Downhill (where it slides through sand); World BowserWorld Bowser icon from Super Mario 3D World.-5, Deepwater Dungeon; and World StarWorld Star-1, Rainbow Run. Plessie also makes a few cameos outside of these levels. In World CrownCrown Icon from Super Mario 3D World-Crown Icon from Super Mario 3D WorldCrown, Champion's Road, it appears at the end of the stage alongside other friendly non-playable characters to congratulate the player. It also appears in the game's title screen, and in the credits scene. Plessie also is the stamp for Plessie's Plunging Falls.

To control Plessie, players can tilt either the control stick or control pad, depending on the controller. To speed up and slow down, players tilt up and down respectively. Players can also press the jump button to jump, which can be used to defeat enemies and reach higher ground. If more players are riding Plessie, they can cooperate to tilt it further. If Plessie falls off of a course, however, the lives lost are dependent on the amount of players riding it.

Plessie also appears in Bowser's Fury, where it helps Mario traverse the waters of Lake Lapcat by carrying him on its back. Like in Super Mario 3D World, Plessie is able to swim and slide on ground. However, the player now has full control over Plessie's movements, and can also use a new move to dive underwater. While underwater, Mario can dodge enemies and Fury Bowser's attacks. If the player presses the jump button as soon as Plessie exits the water, it will launch forward with a sparkling effect, enabling for faster travel. Additionally, its head appears on Plessie Medals.

Plessie must be used in the final boss battle of the mode against Giant Bowser, where it must ram into his crystal ball to damage it. At the end of the battle, Plessie collects the three Giga Bells simultaneously and becomes Giga Cat Plessie to defeat Bowser. The final cutscene of the game ends with the camera zooming out to reveal that said cutscene took place on Giga Cat Plessie's back. Following this, Plessie permanently stays as Cat Plessie, despite returning to normal size; in this form, it can carry kittens on its back.

Super Smash Bros. Ultimate[edit]

Plessie appears in Super Smash Bros. Ultimate as a support spirit. It gives fighters the ability to remain in the water indefinitely. The fight to capture the spirit takes place on Great Bay, against a giant Yoshi simulating Plessie.

Physical appearance[edit]

Despite being named after plesiosaurs, Plessie is designed after a bipedal nothosaur. Plessie is three to four times as tall as Mario, although the artwork made for the Super Mario 3D World Original Soundtrack shows it being around only twice as tall as Mario. Plessie is visibly fat, and this trait is actually used to slide on its belly outside bodies of water. The bottom of each foot, including the toes, is fully covered by a white pad. The back features four darker stripes with rounded borders that are perpendicular with respect to the tail. Plessie's head features two big eyes, each with an orange eyelid, a white sclera, and a big oval pupil surrounded by an aqua green iris. The upper part of the muzzle is elongated like that of a crocodile, with a white protruding end hosting two nostrils near its top. The tail is long and ends with a three-lobed structure resting on the coronal plane, similar to the crest and having the same cyan color as well. Plessie is always seen wearing a red bandana knotted on the left side of its neck.

As Cat Plessie, it gains fur and cat ears, its tail is replaced with a cat tail, and the soles of its back feet are changed to resemble cat paws; Giga Cat Plessie also uses this appearance, albeit extremely large (larger than both Giga Cat Mario and Fury Bowser).

In both Super Mario 3D World and Bowser's Fury, Plessie is given its own theme. In the former, Plessie's theme plays before hopping on Plessie and upon dismounting it in stages such as Plessie's Plunging Falls. The theme is mainly ambience music featuring bongos. In the latter, Plessie's theme plays when riding Plessie. The theme is an upbeat version of Lake Lapcat's theme featuring additional instruments such as violins and trumpets.

Plessie being petted in Deepwater Dungeon.
  • Before and after riding Plessie, the GamePad player can pet it by rubbing it with the stylus. Doing so makes it laugh and give them five Coins.
  • The music that plays while riding Plessie in the levels he appears in is an arrangement of "Slider" from Super Mario 64.
  • The official European sites of Super Mario 3D World feature a short description of Plessie in which it is stated to be a dinosaur,[4][5] referring to it as a male in languages where the term dinosaur is typically male. However, in the German translation of the Super Mario Bros. Encyclopedia, where Plessie's species is not stated, it is referred to as being female.[6]

On the other hand, in the Game World section of the official German site of Super Mario 3D World, Plessie is described as being a dinosaur (Lerne Plessie, den freundlichen Dinosaurier, kennen, der total gerne durch Stromschnellen gleitet!) and is thus referred to as male, as can be seen by the use of den freundlichen Dinosaurier and der.
