Grickle consumes berries that become berry juice within its body. It sticks to walls or trees to mark them with its berry juice, though it's not known if this is a territorial action or something else entirely.

A Grickle hides under rocks, keeping its body concealed inside its shell while eating stored berries. Born from polluted sludge in the sea, Grickle's favorite food is anything filthy.
