The Rhinobug is a common enemy in the Deep Jungle zone. Its ground/melee attributes and damage make it inferior to the other two hostile enemies of the Deep Jungle. However, if it does touch the player, it will inflict +20% Poison damage, making it an annoying obstacle to avoid. It charges at the player occasionally, trying to get an upper hand in battle. It sometimes drops Monster Claws on death.

The Rhinobug gains additional health and damage on Challenge Level 1 and above, but does not change appearance.
