They would be the final boss of Sweet Tooth's story campaign on Sunsprings, California. When one of the monster trucks is defeated, the other monster truck will cover itself in complete metal to make it indestructible unless Sweet Tooth and his gang can get underneath the monster truck so one of his gang members can climb inside of the monster truck to plant a bomb before Sweet Tooth can detonate and destroy the armor. Then Sweet Tooth has to destroyed the monster truck to finish off the Brothers Grimm.
