Krykkani
From Tardis Wiki, the free Doctor Who reference
Krykkani were giant soil-eating creatures who lived underground and resembled lobsters. In the alternate timeline that Ellie Green called "Sahara City", the Krykkani took over Earth and their mineral consumption turned the planet's surface into a desert. They also created sink holes with their many tunnels. (PROSE: Red Rover Red Rover)
