Cat Bus in My Neighbor Totoro is perhaps not anthropomorphized but feline-o-morphized. I am not sure if this is a bus-like a cat or a cat-like bus. Anyway, watch My Neighbor Totoro.
Bertie and Bulgy are two bus characters from Sodor, but they are diminished in the television versions of this rail-supremacist tale. Bertie merely is inferior to Thomas, but Bulgy is the butt of much jokes, being turned into a chicken coop. The magazine writers seem to have redeemed him into a play bus.
