I think "canister-vacuum-like-thing" would come to mind first, to be honest.

This makes you realize why Marvel made the brave decision to drop speech balloons from the cover - there's really no useful information contained in that fellow's utterance, and it's unlikely any kid would pick up the book because a guy falling off a bus took the time to shout RUN FOR YOUR LIFE to the other guy thrown into the air. Thanks for the tip, Mac! I'll do just that.

And while we're at it: what does a Pirate Brain! have to do with any of this? Is the Upright Oreck of Doom somehow controlled by Jean Lafitte's preserved cerebellum?
