Grock Dens

The Grock Dens are the portals of the Grocks, allowing them to emerge at dusk into the outer world.

The crystal plug closes a den and prevents the emergence of the grocks for a short time or until Dillon shatters the plug. But this crystal is onlt avalible in Dillon's Rolling Western.

Trivia

 * The only grocks to not emerge from dens are Veggrocks, their red counterparts, Snaggrocks, and the Ultimogrock.
