- "This new grock type was first discovered inside the Ultimogrock. It's believed to be part of Ultimogrock's natural defenses."
- "A new creature discovered last year inside an ancient life-form. As it lives inside a Wheelgrock, it seems to function as an antibody for its host."
The Crysgrock is a new variety of Grock that only appears in the Ultimogrock and the Wheelgrock, protecting its core alongside Diamongrocks. They are like a recolored Footgrock, except stronger. They reappear in Dillon's Rolling Western: The Last Ranger.
Crysgrocks fight in the exact same way that Footgrocks do, with simple head-attacks.
Crysgrocks have enormous defense on the other hand, taking much longer to defeat even with high-leveled gear. They are also found in groups, sometimes alongside Diamongrocks as well.
- Crysgrocks, despite their name, are in fact orange- and brown-striped grocks.
