Nidoo in its true shape.

Nidoo is a rare enemy appearing in Kirby's Dream Land 3 and certain levels in Kirby: Triple Deluxe. It disguises itself as a door at first, but reveals its true form to be that of a black blob with a pair of glowing eyes as soon as Kirby gets near. In this form, Nidoo jumps around, pausing between jumps, and can harm Kirby by bumping into him. Any attack can defeat it in its blob form, but it is invincible while disguised as a door. Despite their ability to attack, Nidoos will relinquish no ability.

It is notable that a Nidoo assuming the appearance of a door is always black, even if the real doors inside the same area are of a lighter shade.

In Kirby: Triple Deluxe

Nidoo reveals itself and is about to slam onto Kirby.

Nidoo returns in Kirby: Triple Deluxe, once again disguising itself as a doorway. It can be distinguished from real doorways in that it has a bluish tint, where other doors are either black or white. When activated, Nidoo attempts to squish Kirby, then disappears, making the same sound that the Sphere Doomers from Kirby's Return to Dream Land make when attacking.

Nidoo also disguises itself as a platform, and will disappear shortly after Kirby sets foot upon it, usually revealing a void or a spike pit beneath.

In Wild World - Stage 3, Kirby can find a series of paintings of doorways, which are Nidoos in disguise. The Nidoos can be burned away by exposure to sunlight, revealing the true doorway.


  • In Kirby: Triple Deluxe, Nidoo's slamming attack can hurt enemies as well as Kirby.
