Crunk and Chunk (voiced by Kyle Rideout and Vincent Tong) are a pair of Cementasaurs from Dinotrux who are constantly together.
The antisocial Trux, believing that Ty wants to destroy everything they've built in their territory, trap him in a pool of slowly hardening cement. Waldo, who suggested the trip to the Outlands in the first place, goes after the pair to convince them to help save Ty. Unfortunately, they are attacked in the process by Scrapadactyls, but Waldo's quick-thinking enables Ty to escape. With the predators driven off, Crunk and Chunk come to the lava channels and seal them, to the relieve of all the Trux-particularly Ton-Ton, who ended up taking charge when Skya and Dozer kept bickering.
