Tuesday - the curse of the blue spots
(Book)

Excitement is spreading through the halls of Dash Candoo's school. The Face-Pulling Championships are about to begin, featuring students holding their faces in such positions as the Vibrating Jaw-Drop with Eye-Roll and the Dripping Stare of Death. Dash and his classmates have been getting ready for this day for ages. But then, suddenly, right before the championship, blue spots appear on everyone's faces...except for Gronville Honkersmith's face, which remains spotless. Something very suspicious is going on here. Dash needs to act fast to get rid of the spots...or else he and his friends will be pulled from the Face-Pulling for sure.--,Publisher's description.
