Manolo is an obese human truck driver who is seen riding in Roco's truck along with his pet Roco. He is always asleep, and as such Roco is the one who actually drives the truck with a system of pulleys. Roco is very fond of him, although it was shown in flashbacks that Manolo was always asleep even when Roco was a puppy. As such it's entirely unknown if Manolo even knows he has a dog (or that he is delivering cargo in the desert.) It was shown in the episode "Radio Active" that music can cause Manolo to sleep dance, which Roco has used to beat up on Oscar and the Trio for stealing his cargo. Unfortunately for Roco, this scheme ended with Manolo falling on him and Roco being trapped under his considerable bulk.
