Unera

Unera are Bee larvae from the Tree Zone level Honeybees in Super Mario Land 2: 6 Golden Coins. Unera are one of the easiest enemies in the games to defeat. They crawl along the floor and turn around when they reach a ledge. Mario can defeat one by jumping on it, hitting it with a fireball, or touching it while invincible. A more mature, spiked version of Unera is known as Grubby.
