Goombrat

Goombrats are a species of Goomba that debuted in the Wii U title New Super Mario Bros. U. They are short, are lighter brown, and resemble persimmons more than mushrooms. They have wider eyes in a scowl instead of eyebrows, and the black stems on their head are similar to tomato leaves. They also turn when they reach edges, which is similar to the behavior of red Koopa Troopas. The enemy's name is a composition of "Goomba" and "brat". Additionally, their teeth point down and have a curved shape, while regular Goombas' teeth point up and are sharp. The teeth look similar to how Goomba teeth do in Super Mario Bros. 3

These sub-species only appear in the sky level of Acorn Plains, Mushroom Heights, and one of the levels in Challenge Mode, The Goombrat Stomp.

In New Super Luigi U they are significantly more common.

Goombrats reappear Mario Party 10, seen in some minigames alongside Goombas and Galoombas. They also appear in Mario Party: Star Rush.
