Pokey Head

Pokey Heads, also referred to as Pokey Sprouts or just Pokeys , are enemies appearing in Super Mario Sunshine, Super Mario Galaxy, and Super Mario Galaxy 2. They are similar to a standard Pokey, but include only the head. They are green in Super Mario Galaxy and Super Mario Galaxy 2.

Unlike standard Pokeys, they cannot fall on Mario, as they are too small. Instead, they hide in the ground, pretending to be flowers, and jump when he approaches. They then hop toward Mario slowly. They can be defeated with a stomp or spin. Additionally, they can be sprayed into a wall in Super Mario Sunshine. This causes them to splat on the wall and produce three coins instead of one.

Trivia

 * The overworld sprite of Pokeys in Mario & Luigi: Partners in Time appears similar to a Pokey Head.
 * They can be watered like normal flowers in Super Mario Sunshine before they attack, but this does not produce coins like a real flower. They do not make noises either.
