The Field Day from the Black Lagoon, Paperback

Another fun chapter book about field day and sports from the dynamic duo of Mike Thaler and Jared Lee - just in time for summer
There's just one week until field day at the Black Lagoon and Hubie is going to be ready
But getting in shape in one week is harder than he thinks -- especially when the workout kit he has seems to be for chickens. Why else would he be developing his pecs and thighs?
When the two teams finally meet on the big day, there's more than winning at stake. Will their friendships survive the cut-throat water balloon tosses and three-legged races that await them?
