Editing Koopa Troopa

In ''[[Super Mario Bros.]]'', Koopa Troopas are the second enemy [[Mario]] encounters, directly after [[Goomba]]s. They serve as foot-soldiers in the army Bowser uses to invade the [[Mushroom Kingdom]]. If jumped on, a Koopa Troopa recedes into [[Koopa Shell|shell]], which can then be kicked to attack other enemies. If [[Super Mario (form)|Super]]/[[Fire Mario|Fire]] [[Mario]] gets hit by the shell, he reverts to [[Small Mario|Small form]]; Small Mario loses a life instead. If a Koopa Troopa's shell is left alone for too long, however, the Koopa reemerges (their legs flash rapidly as a warning). The game features two different types of Koopa Troopas: green, which walks in one direction until it is defeated or falls and appears darker in underground and castle levels; and red, which patrols a set area without walking off any edges. Sometimes, if a Koopa Troopa is either hit from below or is [[stomp]]ed while falling, the shell is flipped upside down (like with its death animation), although if left alone long enough, the Koopa will right itself back up. The game's instruction manual claims that red Koopa Troopas are timid and get scared easily as the reason for them not falling off cliffs. There is also a variation to the Koopa Troopa known as [[Koopa Paratroopa]]s, which are flying Koopa Troopas. A Koopa Troopa is one of seven [[Impostor Bowser|fake Bowsers]] that serve as the bosses of the castles in the first seven worlds, particularly in [[World 2-4 (Super Mario Bros.)|World 2's castle]]; its true identity will be revealed if it is defeated by [[fireball]]s.

Koopa Troopas reappear in ''[[Super Mario Bros.: The Lost Levels]]'' working exactly the same way as in the previous game. However, they walk faster than before, making them harder enemies for Mario or Luigi to handle. They can now be found underwater, where they cannot be stomped. Unlike the ones on land, these Koopas have gray shells like the gray [[Cheep Cheep]]s that are normally found underwater (but are colored normally in the SNES remake; red Koopas, along with other red enemies, remain the same color regardless of whichever palette is used), suggesting that green/orange enemies are always colored gray/orange when using the underwater palette, as evidenced by the fact that gray Cheep Cheeps were recolored green in ''[[Super Mario All-Stars]]''. In the ''Super Mario All-Stars'' version, the fake Bowser fought at the end of World A's castle is actually a red Koopa Troopa, though it is depicted as a right-side-up Koopa instead of an upside-down one.
