Pokey Head

Pokey Sprouts are enemies appearing in Super Mario Sunshine, Super Mario Galaxy, and Super Mario Galaxy 2. They are similar to a standard Pokey, but only include 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 out when the plumber approaches. They then hop towards Mario slowly. They can be defeated with a Jump 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 identical to a Pokey Sprout.
 * 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.
