Bigchukkas look like small Hulks, and are only armed with a single Bigchukka catapult. They use a complex system of gears to wind and load their Bigchukka catapults. Unfortunately, this system of gearing is also used to power the treadwheel, meaning the vehicle cannot move and fire at the same time. Bigchukkas are sometimes towed to the area of a battle by Hulks then loosed to "Do da bizness," as some Orcs would put it.[1a]
