Chikako

Chikako (Glitter), also known as Chikaka, are robotic enemies that float slightly up and down in the skies of the Chai Kingdom during the events of Super Mario Land. They can be shot ten times with the Sky Pop's missiles to destroy it, awarding Mario with an extra 800 points. Chikako only appear in World 4-3, the Sky Pop's level. Chikakos somewhat resemble computer monitors with antennas.
