Slime Bot

The Slime Bots are a group that appears in the Sonic Boom television series. It is a decommissioned robot line created by Dr. Eggman whose members are characterized by their slime emissions.

Description
Slime Bots, as outlined by Dr. Eggman, are robots covered in a disgusting green goo (hence their name), which they constantly excrete as saliva and perspiration. Because the only known Slime Bot is Buster, other constants pertaining to the Slime Bots remain inconclusive.

Season one
The Slime Bots were designed by Dr. Eggman. A particular Slime Bot dubbed "Cluster Bot" was used by Eggman for a scheme to destroy Team Sonic. However, when Cluster Bot turned against Eggman, the doctor vowed to never make a Slime Bot again.

Trivia

 * The Slime Bots are the only robot line created by Dr. Eggman (besides the Orbot Series) to only have one member revealed.
