Grumbo is the god of all crabs. May his pincers protect you against the sinister brothers, Balbus and Bumpus. Grumbo seeks to face the brothers sinister head on, rather than suffer their trickery. A bold plan, but foolhardy. Many a shattered exoskeleton lie outside the Brothers' shack in the salt wastes.
It is murky what Grumbo's intentions for the ocean may be, with most reef dwellers assuming positive changes. He busies himself in commanding raids and attacks on strongholds and uprisings caused by the Brothers. In that, there is some silently bubbled speculation his drive for justice has clouded the ultimate goal of his ambitions.
