Ben is quite agreeable, though he is frusterated with the lack of brothers to talk to
He and his best friend Rafael have an obsession with outer space and astronaut, and Ben acquires a short-lived fascination with Minnesota in the Penderwicks in Spring. Ben also loves dinosaurs and all rocks
He has a fascination with interesting Or unlikely facts, most of which his BFF Rafael makes up.
Ben has a wild imagination that he often builds into his world (he has a large box of action figures and model airplanes behind the bushes beside the Penderwick house.)
