From Melvor Idle

Not much is known about Coolrox, but what we can say is Coolrox was hired by Malcs to develop the Combat Rewrite and Offline Combat systems for V0.21, and is now an assumed part time coder to help out with future updates.

Coolrox is a large fan of Lemons.

Coolrox has the Cool Rock Pet, as well as the Cool Glasses Secret that can be assumed to be a bonus for helping out with the Combat Rewrite. Cool Rock (pet).svg
