Sushi

Sushis are blue shark enemies found in several Mario games. They have navy-blue colored scales and a long pointed nose. Their name comes from the Japanese dish, sushi.

Super Mario 64 / Super Mario 64 DS
Sushis first appear in Super Mario 64, where they can be found in Dire, Dire Docks. These sharks swim around, minding their own business. There is no way to attack them and they usually won't bother Mario, unless he accidentally swims into them. They also reappear in the DS remake, Super Mario 64 DS, acting the same way as they did in the original.

New Super Mario Bros.
Sushis make a minor appearance in New Super Mario Bros., only appearing in World 1-A. They travel two at a time, swimming horizontally at different heights on the screen. They can be defeated with fireballs or a Starman.

Mario Party
In the Mario Party minigame Treasure Divers, a Sushi appears swimming around alongside two Bloopers.

Mario Party 2
In Mario Party 2, one appears in Pirate Land, and will ferry anyone who lands next to the dock of one island to the dock on the opposing island, charging five coins per trip.

Mario Party 3
In Mario Party 3, a Sushi appears in Deep Bloober Sea, and is in charge of the torpedo controls. This Sushi will ask everyone who passes to push one of four buttons upon reaching a fork; one of them serves as the detonator, which will fire a torpedo when pushed, forcing the player to take the path they didn't select. A Sushi is also present in the minigame, Dizzy Dinghies.

Mario Party 4
Sushis appear as obstacles in Manta Rings, where hitting it deducts two points from the player.

Mario Party Advance
In Mario Party Advance, a Sushi lives at Sushi Cliff.

Mario Party 7
In Mario Party 7, the 1-vs-3 minigame Be My Chum! involves the lone player calling out names of various enemies (including Sushi) on the Nintendo GameCube Microphone to attack the other players. They simply swim straight forward in a speedy manner.

Mario Party 9
In Mario Party 9, Sushis only appear on the board Blooper Beach. They appear after the player runs into a Dolphin. They advance from behind the player, moving four spaces per turn. If they catch up to the vehicle, then the player loses half of his or her Mini Stars; it is then replaced by a Dolphin. If the player is near the first Boss Battle Space when a Sushi is the active fish, it swims away. Notably, Sushis are one of the few characters seen in the game that do not have a constellation based off of them.

Mario Hoops 3-on-3
In Mario Hoops 3-on-3, the course Bloocheep Sea has Sushi swimming in the background.

Mario Kart Arcade GP DX
In Mario Kart Arcade GP DX, a large statue of a Sushi can be seen above the race courses Splash Circuit and Tropical Coast.
