Slugbulbs live in caves that usually have Glow-worms and Eletricstickys living in them as well.

Physical Appearance

Slugbulbs are small glowing dragons with a toothed mouth, a tail, an a round body. They appear to have filaments or tentacles of some sort. Some depictions show small knobs. They have one pair of wings. They also don't appear to have any eyes in their images.


Slugbulbs appear to be able to glow or fluoresce based on their pictures and name.


Slugbulbs have weak eyesight and usually run into things and end up falling into bowls. Because of their small size, they can drown in the shallowest amounts of water.
