In my world these are the garbage trucks. People get on these big blind lizard creatures (that smell horrible and can eat anything) and have someone follow them from behind and feed the beast's hind quarters nasty garbage. Then they sell the purquiliaevore's poop as fertilizer. win win situation. yes. Purquiliaevore is a mixture of Latin words that basically mean big garbage eater. It's about 6ft tall from the very top hump and it's head and jaw are about 3 ft from the ground, it's around 16 ft long.
