Clampys[1] (also known as simply clams[2][3]) are giant clam enemies that debuted in Super Mario Galaxy. They open and close their valves periodically, often revealing items inside their cavities. The player can collect these items and swim away before getting caught inside the Clampy as it closes its valves.


Super Mario series[edit]

Super Mario Galaxy[edit]

One cream-colored Clampy first appears in Super Mario Galaxy, being encountered in the Beach Bowl Galaxy. Much like the clams in Super Mario 64, it holds treasures inside such as Star Chips and coins, depending on the mission selected.

New Super Mario Bros. Wii[edit]

Clampys make their first 2D game appearance in New Super Mario Bros. Wii, only appearing in World 1-4 and in a secret area in World 4-1. They were slightly reshaped, and now display a purple coloration with darker wavy stripes, which would stick to them in most future appearances. They have coins or 1-Up Mushrooms between their valves in order to lure a character close so they can attack them. If a Clampy closes its shell in on a character, it will trap them inside for a brief moment and damage them before opening back up. However, their top shells (when closed) and the inside of their cavities (when open) are safe to tread on. In general, Clampys spawn in mid-water and slowly sink to a ground underneath, after which they begin their routine of opening and closing their valves. One Clampy in World 1-4 slips into a pit after touching the ground.

Super Mario Galaxy 2[edit]

A single Clampy appears in Super Mario Galaxy 2, behaving and looking identically to the species' initial appearance in Super Mario Galaxy. It appears on the seabed in Starshine Beach Galaxy.

New Super Mario Bros. U / New Super Mario Bros. U Deluxe[edit]

Clampys, referred to as Giant Clams[4], appear in New Super Mario Bros. U and its port, where they act exactly like they do in New Super Mario Bros. Wii. One can be found in a secret area of Waterspout Beach, while multiple inhabit World Coin-5. They do not return in New Super Luigi U.

Mario Kart series[edit]

Mario Kart 7[edit]

Clampys appear in the Cheep Cheep Lagoon and GCN Daisy Cruiser racecourses in Mario Kart 7. They are obstacles that are found only underwater, containing coins and Item Boxes between their valves that racers can pick up, taking care not to be trapped by the Clampy's valves. Racers can perform tricks on them when they are open.

Mario Kart Tour[edit]

Clampys reappear in 3DS Cheep Cheep Lagoon, GCN Daisy Cruiser, and Piranha Plant Cove 2 and 3 in Mario Kart Tour, acting the same as they did in Mario Kart 7. They are able to spin out drivers in a Bubble without popping their Bubble. The Item Boxes that Clampys produce, if broken, do not respawn immediately unlike other Item Boxes.

Mario Kart 8 Deluxe[edit]

Clampys return in the Booster Course Pass DLC for Mario Kart 8 Deluxe, where they once again appear in GCN Daisy Cruiser and Piranha Plant Cove, acting the same as they did in previous entries.

Mario Party 10[edit]

Clampys reappear in Mario Party 10 in the background of the board Whimsical Waters. They also appear in the minigame Cheep Cheep Check, where they are used by the solo player to disperse large clusters of bubbles meant to distract the other players from counting the Cheep Cheeps.

Dr. Mario World[edit]

A Clampy appears as an Assistant in Dr. Mario World. When equipped in stage mode, there is a chance that the rainbow meter is filled by three sections when the stage starts. In versus mode, it grants doctors an extra chance to defend against opponent's attacks.

Profiles and statistics[edit]

New Super Mario Bros. Wii[edit]

  • Trading Card description: It looks like an open and shut case with this enemy. Clampy lurks in the depths of the sea, patiently waiting to make a move. Clampy will try to clench you in its shell, causing a loss of power—or worse! However, sometimes there a 1-Up mushroom in them, so it may be worth messing with this mollusk. Don't clam up—swim fast, grab the goods, and get out!

Card Number: 34 (Normal), F19 (Silver)
