- Dolphin

Dolphins are goggle-wearing cetaceans that debuted in Super Mario World. Here, they act as platforms that leap out of the water, helping the playable character reach items or avoid enemies. In other Mario-related media, Dolphins typically appear as background elements, though they have more prominent roles throughout the Mario Party series and a particular Dolphin even had a playable role in Dr. Mario World.

Super Mario World / Super Mario World: Super Mario Advance 2
Dolphins only appear in Vanilla Secret 3 and in a hidden area near the end of Chocolate Island 1. They are used as platforms to cross a body of water populated by Porcu-Puffers. They jump in and out of water either vertically or in parabolic arcs. In the Japanese version of Super Mario World, Yoshi can eat the Dolphins. This was changed in Western versions of the original Super Mario World, but was retained in all versions of Super Mario World: Super Mario Advance 2. They also appear in the opening sequence of Super Mario World: Super Mario Advance 2.

Super Mario World television series
In the Super Mario World television series, Dolphins appear only in the episode "Mama Luigi". Seeing that Luigi and Yoshi are being attacked by a Torpedo Ted, two Dolphins decide to help them by letting them ride on their backs. Evading the Torpedo Ted, the Dolphins drop Luigi and Yoshi off at a nearby beach. After being thanked by Luigi, the two friendly Dolphins leap back into the water, cheering happily.

Nintendo Adventure Books
A Dolphin is featured on the cover of Dinosaur Dilemma, and artwork of one is used in the book, but none appear in the actual story. An equally friendly sub-species of them, the Micro-Dolphins, is discovered to be living inside Yoshi in Unjust Desserts.

Super Mario-kun
Dolphins appear in the second chapter of the second volume of Super Mario-kun as allies. When the Mekakuppa attacks Mario, Luigi and Yoshi at Vanilla Dome, it creates a hole in the roof, flooding the dome with the water of Vanilla Secret 3. Dolphins come down with the water and offer to help the three heroes to escape by making them ride their backs and swim over the waterfall, reaching the surface. Mario then proceeds to clog the hole, trapping (briefly) the Mekakuppa in the dome and then proceeds to thank the Dolphins, along with saving them from Yoshi (who kept trying to eat them).

Mario Party 4
A Dolphin appears in Koopa's Seaside Soiree in Mario Party 4, where he will let the character played as get on his back while he swims through the water. The character can Jump to get Coins this Dolphin swims by on the trip.

Mario Party 8
In Mario Party 8, the Dolphins play an important role in the board Goomba's Booty Boardwalk; players can pay them a certain number of coins depending on what place they are in, allowing them to take a ride on the Dolphin's back and advance a number of spaces.

Mario Party 9
In Mario Party 9, Dolphins appear on Blooper Beach. On the first half of the board, a Dolphin is the first active sea creature when a party is started, being six spaces away at first. They advance two spaces every turn, and if the player lands on or catches up to the dolphin while captain, the Dolphin gives them 5 Mini Stars. Dolphins also appear when the player lands on a Lucky Space near the end of the board. Landing on one of them results in a trio of Dolphins leading the player to an island with several Mini Stars. Additionally, during the minigame Ring Leader, the players ride Dolphins to jump through hoops.

Mario Party: The Top 100
In Mario Party: The Top 100, a Dolphin makes a cameo appearance in the Collection mode, appearing in Mario Party 9's box art.

Mario Kart Arcade GP DX
Dolphins make their first cameo appearance in the Mario Kart series in Mario Kart Arcade GP DX, where they can be seen jumping out of the water in the Splash Circuit and Tropical Coast stages. A kart based off Dolphins called the Turbo Dolphin appears in the game.

Mario Kart 8 / Mario Kart 8 Deluxe
In Mario Kart 8 and Mario Kart 8 Deluxe, there is a banner with Dolphin artwork from Super Mario World on it found in Toad Harbor. Also, Dolphin Shoals features Dolphins that act similarly to those in Mario Kart Arcade GP DX, as well as Dolphin-shaped hill structures. In Sunshine Airport, this course can be seen listed on the signboards in the terminal next to other courses.

Mario Playing Cards
A Dolphin appears on the three of clubs in the NAP-06 deck of the Super Mario Bros. 30th Anniversary release of the Mario Playing Cards.

Dr. Mario World
Dolphins appear in Dr. Mario World as assistants. Their stage mode effect increases the player's base score for every blue virus that are eliminated. Their versus mode effect grants a chance one of the viruses that appear is transformed into an exploder when all viruses in the player's play area are eliminated. The amount of points gained and the chance of an exploder appearing are increased at higher levels, starting from 50 points and 20% respectively to 200 points and 100% respectively.

A Dolphin also appears as a playable character under the name Dr. Dolphin, marking the first time a Dolphin has been playable in any Mario game. His skill effect is the same as Dr. Bowser Jr.'s in that in stage mode an amount of bubbles are popped, while in versus mode viruses are covered inside bubbles. The amount of bubbles or viruses targeted are fewer than Dr. Bowser Jr.'s skill, where Dr. Dolphin's skill pops 4 bubbles (3 prior to version 2.2.0) as opposed to Dr. Bowser Jr.'s 10, while in versus mode at maximum level, Dr. Dolphin covers up to 6 viruses inside bubbles as opposed to Dr. Bowser Jr.'s maximum of 10. To compensate, his skill charges faster compared to Dr. Bowser Jr.'s.

Other appearances
In the Super Mario Mash-up of Minecraft, regular dolphins are reskinned as Dolphins from the Mario franchise.

Trivia

 * The fish enemies Blurp and Bub are visually comparable to the dolphins.
 * Isle Delfino, the setting of Super Mario Sunshine, is shaped like a dolphin.
 * In Super Mario 64 DS, Dorrie was redesigned with elements seemingly influenced by the dolphins. This design is the basis for all of Dorrie's subsequent appearances.
 * The rival character Guppy from Super Mario Galaxy was initially envisioned as one of the dolphins from Super Mario World. However, as his role was finalized as an intimidating bully with a wild nature, they shifted his design to that of the new orca character seen in the final game.
