|“||Some enemies do it for respect, but Grinkey is in it for the thrill of the chase. He spends so much time running away from people who want to unlock doors that he never remembers to lock his own door.”|
|— Figurine description • Kirby and the Rainbow Curse|
Grinkey is a large golden key. He has a brown face, glaring yellow eyes, and a malicious grin. He has a ruby attached to his hilt and golden wings growing from his head.
A single Grinkey appears in the stages The Long-Lost Ruins and Wonder Space. Clay engulfs a key, transforming it into the mischievous foe. He flies around the room aimlessly, damaging Kirby if the two collide. To recover the key, the pink puff must hit Grinkey with three Tap Dashes or a Star Dash.
Grinkey's name is a combination of the words grin and key, referencing his perpetual smile and key-like appearance.
