Like any of nature's creations,frogs are unpredictable-that is,unless they have been to Bill Steed's famous Croaker College. Steed's "students" are given a 240-hour frog training coure to teach them the fundamentals of frog jumping under pressure.At Croaker College,the frogs work out in a pool,lift tiny weights, do chin- ups and high dives eat centipede soup and ladybug salad, and generally prepare for the big day. Do graduates of Croaker College really win frog-jumping contests more often? That's a question Jom Steed prefers not to answer.
