Shellcreeper

Template:Species-infobox Shellcreepers are green-shelled turtles that first appeared in the Mario Bros. arcade game. They are the first turtle enemies to appear in a Mario game, making them the conceptual ancestors of the Koopa Troopas, which appeared two years later in Super Mario Bros.. It is also shown that Shellcreepers wear undershirts and shorts when outside of their shells; Koopa Troopas first appeared out of their shells in Super Mario World wearing a shirt, and in Super Mario World 2: Yoshi's Island wearing shorts.

History

Mario Bros.

Mario jumping over a Shellcreeper in Mario Bros..

The Shellcreeper is the first enemy to appear in Mario Bros.. They walk out of the Warp Pipes at the top of the screen and walk towards the pipes at the bottom of the screen. The player must hit it from below to flip it over and run into it to defeat it. If the player does not run into it, the Shellcreeper jumps out of its shell (revealing that it wears a white shirt and shorts), flips its shell over, changes color from green to purple and continues moving faster than before. If it flips its shell again, it will turn red, its fastest state. If a Shellcreeper is the last target for the phase, it will automatically turn red. Unlike the similar Koopa Troopa, jumping on Shellcreeper will cause Mario or Luigi to lose a life.

Following the Mario Bros.-style minigame in Super Mario Bros. 3, Shellcreeper has been replaced by Spiny in all subsequent versions, so they would not be mistaken for a Koopa Troopa, which is safe to jump on. Despite this, a lone Shellcreeper still makes a cameo alongside a Sidestepper and Fighter Fly on the Game Boy Advance Mario Bros. title screen.

Mario Power Tennis

Shellcreepers, along with the other Mario Bros. enemies, appear in the background of the Mario Classic Court in Mario Power Tennis.

Super Smash Bros. Brawl

In Super Smash Bros. Brawl, Shellcreepers appear on the Mario Bros. stage. They walk out from the pipes at the top of the stage. If knocked over by hitting them from below or from an attack, they can be picked up and thrown at opponents, making them fly sideways off the screen. The Shellcreepers also have their own trophy.

Super Mario 3D World

Shellcreepers appear in Luigi Bros.; an additional game featured in Super Mario 3D World. Like the other enemies in Luigi Bros., Shellcreepers behave in the same way as Mario Bros., which this game is based on.

NES Remix

Shellcreepers appear in NES Remix in the challenges and remixes based on Mario Bros.

Shellcreepers		NES Mario Bros.	Shelled enemies Mario and Luigi faced back when they were plumbers. They had to be bumped from below to flip them over and then kicked off the stage. The last one on a stage turned from green to red and raced really fast. If one got flipped but not sent off, it would eventually right itself and move at high speeds. They were simply called "turtles" in Japan.

	ARCADE Mario Bros. GBA Super Mario Advance	With a name that implies silently sneaking up on its prey, the Shellcreeper might be considered cooler than your average turtle. The Koopa is apparently an evolved form of this veteran of Mario Bros. We'd recommend not jumping on this one like you would a Koopa, though...
