“Harry! Good-o!” said Bagman happily, looking around at him. “Come in, come in, make yourself at home!”
Bagman looked somehow like a slightly overblown cartoon figure, standing amid all the pale-faced champions. He was wearing his old Wasp robes again.
(p349, Harry Potter 4, US edition)
According to a dictionary at hand, ‘overblown’ means ‘exaggerated’. I’m thinking ‘overblown’ in the above quotation is used to contrast against ‘pale-faced’ champions. However, I can’t get what is exaggerated for sure; The color of robes? His happy face? Therefore, I can’t imagine such cartoon figure at all.
What does “a slightly overblown cartoon figure” mean? What kind of picture would you get from it?
