Grinders,[1] also named Monkeys, are a type of monkey enemy featured in the Yoshi's Island series. They first appear in Super Mario World 2: Yoshi's Island, and are typically found within jungle areas.


Yoshi's Island series

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3

In Super Mario World 2: Yoshi's Island and its Game Boy Advance remake Yoshi's Island: Super Mario Advance 3, Grinders attack Yoshi in a variety of ways, including by spitting seeds, dropping bombs, and grabbing Baby Mario. If hit, a Grinder turns a darker shade of brown and run away. Some Grinders are harmless and simply run around the stage. A Grinder usually jumps onto a vine and climbs it as high as possible, but if a Yoshi gets too close to a Grinder, it runs away again. Because of their speed, Grinders are hard for Yoshi to catch.

A Grinder can be stunned with a Yoshi Egg or a stomp, after which Yoshi can defeat them by eating them or running over them while they are unconscious. A Grinder can also swim slowly in water, and cannot be defeated while doing so as stunning it instead causes the Grinder to "flail" in place.

Yoshi's Island DS

In Yoshi's Island DS, they are named Monkeys. All of them are harmless, and they can be defeated from any attack. Monkeys are no longer invulnerable while in the water. Monkeys retain their agility, making them still difficult to catch.

At the start of the level Baby DK, the Jungle King!, one Grinder kidnaps both Baby Mario and Baby Peach.

Yoshi's New Island

In Yoshi's New Island, they are named Ukikis. Unlike earlier Yoshi's Island titles, they cannot be eaten.
