Bulber

Bulbers are angler-fish-like enemies that appear in New Super Mario Bros. Wii. They only appear in World 8-4 with the same function as the Jellybeams. They illuminate the way for the player. Bulbers swim freely in the water, illuminating the area around them. Bulbers can be defeated by attacking them with a fireball, by freezing it or by running into it with a Starman, although this is not necessary and perhaps even detrimental due to loss of illumination. Bulbers are very passive and will only hurt Mario if he touches them.
