Goombrat

Goombrats are a species of Goomba that debuted in New Super Mario Bros. U. The enemy's name is a portmanteau of "Goomba" and "brat". They are short, lighter brown, and resemble 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, unlike Goombas. Additionally, their teeth point down and have a curved shape, resembling those of in-game Goombas in Super Mario World 2: Yoshi's Island, while regular Goombas' and Galoombas' teeth point up and are sharp.

New Super Mario Bros. U / New Super Luigi U / New Super Mario Bros. U Deluxe
Goombrats debut in New Super Mario Bros. U. They only appear in Mushroom Heights and the Challenge Mode levels The Goombrat Stomp, Spin Jump, Get Dizzy, and The Perpetual Shell. When they reach a ledge, they will look down at it before turning, then look forwards again. Their leaves bounce to the music.

In New Super Luigi U, Goombrats are significantly more common.

Goombrats reappear in the Nintendo Switch port, New Super Mario Bros. U Deluxe.

Super Mario Run
Goombrats appear in the version 3.0.4 update in Super Mario Run, where they appear in the levels Scuttlebug Forest and Spike Bar Jungle. In Scuttlebug Forest, one can be seen with a Super Mushroom on its head. A few other Goombrats glow in a yellow tone, and stomping them will release more coins than usual. A large variety known as the Big Goombrat also appears in Remix 10.

Super Mario Maker 2
Goombrats appear in Super Mario Maker 2, as a variation of a Goomba. Big Goombrats reappear and are created by enlarging Goombrats, and wings can be given to them, allowing them to jump higher than Paragoombas. They have been given new sprites for the Super Mario Bros. and Super Mario Bros. 3 styles, due to them not originally appearing in either of those games.

In the Super Mario World style, similar to how Goombas are replaced by Galoombas, Goombuds are a new enemy that appear similar to the Goombrat, but can be knocked over and carried instead of stomped on.

Super Mario Bros. Wonder
Goombrats return in Super Mario Bros. Wonder. When they collide with each other, they lean to one side for a brief moment before turning around.

Mario Party series
Goombrats reappear in Mario Party 10 in the free-for-all minigames Goomba Gotcha and Goomba Gallop, alongside Goombas and Galoombas, as well as in the 2-vs-2 minigame Goombrat Combat.

Goombrats return in Mario Party: Star Rush, in the free-for-all minigame Acornucopia and the Coin Chaos minigame Samurai Smackdown.

Dr. Mario World
Goombrats appear in Dr. Mario World as obtainable assistants. They also appear in the background of World 9 when an area has been cleared, and can be obtained as assistants after clearing the first area in World 9. In stage mode, their effect is to increase the skill meter by an extra portion if blue viruses are eliminated, so for example if the percentage is 10% the skill meter is filled by an extra 0.1 points per blue virus eliminated. In versus mode, their effect is to grant a chance that the next capsule is a rainbow capsule every time the opponent attacks.
