Big Cheep Cheep

Big Cheep Cheeps, originally Mega Cheep-Cheeps, are large Cheep Cheeps that appear in all five New Super Mario Bros. games. One of them also makes an appearance in Paper Mario: Sticker Star. This type is considered to be one of the largest category of said species.

Super Mario series
In New Super Mario Bros., they will not target Mario or Luigi, but instead will follow a path oblivious to them, just like normal Cheep Cheeps. Big Cheep Cheeps are colored red and are similar to Boss Basses and Big Berthas. Each one is usually followed by about three Cheep Cheeps. In New Super Mario Bros. Wii, their size has been reduced so they appear to just be slightly bigger. However, in New Super Mario Bros. 2, they regain their original size, but in New Super Mario Bros. U its size is reduced again.

Mario Party 8
Big Cheep Cheeps also make a minor appearance in Mario Party 8. In the minigame Rowed to Victory, the losing team of boaters will be chased by a Big Cheep Cheep and a few Cheep Cheeps.

Mario Party 10
Big Cheep Cheeps appear again in Mario Party 10, appearing only in the minigame Cheep Cheep Leap. Any Big Cheep Cheep that gets hit grants two points.

Paper Mario: Sticker Star
A Big Cheep Cheep appears as a mini-boss in Paper Mario: Sticker Star. It is encountered in Surfshine Harbor after Mario sets sail. The Big Cheep Cheep blocks Mario's access to Worlds 4, 5, and 6 as long as it remains undefeated. Comments made by various characters imply that this particular Cheep Cheep is a very rare sight especially given its size. Big Cheep Cheep's body appears to be made with a Chinese lantern.

In battle, the Big Cheep Cheep starts out beached on the pier. All it can do during this time is slam into Mario. After the Big Cheep Cheep takes enough damage, it hops into the water and regain all its HP. From the ocean, the Big Cheep Cheep can spray a powerful jet of water and automatically avoids any attacks from Mario. The only way to be able to attack the Big Cheep Cheep is by using the Fishhook sticker on it since the rest of his stickers can't reach. Doing this beaches the mini-boss once again, causing it to fly into a rage. The Big Cheep Cheep will only be able to slam into Mario after it gets fished out of the water. Each turn, the Big Cheep Cheep grows in size, increasing its attack power. If the Big Cheep Cheep grows large enough, it explodes, dealing 99 damage (40 if using Spike Helmet) to Mario. If it does deal 99 damage, it is an instant Game Over. Once it has been defeated, Mario can safely access the other three worlds.

Alternatively, using sharp stickers like Spike Helmet or Thumbtack when the Big Cheep Cheep attacks during the second phase will instantly defeat it. However, it will also damage Mario for 50 HP. In the PAL version of the game, this damage is reduced to 30.

If a player attempts to use any type of Infinijump sticker, during the first phase, against the Big Cheep Cheep, its HP does not decrease lower than 20 HP and instead, the player receives Coins for every hit dealt to the Big Cheep Cheep after it's health reaches this point.

The Big Cheep Cheep in Paper Mario: Sticker Star is one of two mini-bosses in the Paper Mario series that can be damaged with a First Strike. The other is the Big Chain Chomp from Chomp Ruins from the same game.

Super Mario Maker / Super Mario Maker for Nintendo 3DS
Big Cheep Cheeps reappear in Super Mario Maker and Super Mario Maker for Nintendo 3DS. The player can enlarge a normal Cheep Cheep with a Super Mushroom, turning it into a Big Cheep Cheep.

The Legend of Zelda: Four Swords Adventures
These large-sized Cheep Cheeps first appeared in The Legend of Zelda: Four Swords Adventures, alongside the normal size. They reside in the Desert of Doubt's first stage. They charge at Link and cause critical damage to the hero.
