Romaji: Nokonoko) are a species of Koopa Troopa that block Mario and Luigi's way to some passageways in the game Mario & Luigi: Superstar Saga. They're very large, and if Mario and Luigi talk to them, they will just tell them that there is no way you can knock them down. Once Mario gets his Firebrand dash attack, Mario and Luigi will be able to ram into them, thus knocking them down. Despite being considered enemies, Mario and Luigi never actually battle them in the game. In the remake, they are replaced with Gargantua Koopa Troopas.
Their name is a combination of the words "Anchor" and "Koopa".
