Turtle (Mario & Luigi: Superstar Saga)
From the Super Mario Wiki
“Aaaah! How did THAT happen??? You guys are no slouches!”
Turtles are pudgy, giant Koopa Troopas found only in Mario & Luigi: Superstar Saga. They are cross-eyed and have oblong shells which extend up from their backs, behind their heads. They block certain paths in the Beanbean Kingdom and recite the line, "Derr... No matter what you hit me with, you can't knock me down. ...I think." They cannot be stomped; however, Mario's Firebrand Bros. Dash technique can knock them down, forcing them to move aside. One also appears in a house in Beanbean Castle Town.
