Barbos DKC3

It has a variation to put on the wall or as a fridge magnet and more details than the chess version.

Barbos was the sixth boss in Donkey Kong Country 3: Dixie Kong's Double Trouble!, and the first in Donkey Kong Land III. She is a giant Lurchin, and is apparently the leader of them.
In Donkey Kong Country 3 she appeared in the stage Barbos's Barrier at the end of Razor Ridge. Here, the Kongs would turn into Enguarde, fitting for an underwater battle. Barbos would spawn two Lurchins by her side, and once they were defeated, Barbos would squish up and down repeatedly, try to protect her weak spot. Use Enguarde's supercharge attack when it's open and she will drop down to the second stage.

It will do a similar thing, except Barbos will be invincible and she will now spawn seashell-missiles. Lure the missiles into the shells to hurt them, and get them into her weak spot to advance. Finally, dodge her spike attacks and strike her when it's open.

In the GBA version, she rules over Pacifica, her position replaced by Kroctopus.

In Donkey Kong Land III Barbos returns as the boss of Cape Codswallop, in the stage Barbos Bastion. The Kongs will turn into Enguarde, and must smash three Lurchins into Barbos's face to defeat her. Each time Barbos is hit, she will shoot three Lurchin shells, though note they cannot be attacked.
