Frank and his brother, Joe, have got the school talent show in the bag with their sword fight . . . or so they think. They and their classmates have been working on their talents for weeks, and they can't wait to be onstage showing off!
But then a mystery falls on their heads. Literally. In the middle of the show, frogs start falling from the ceiling onto the competition! Why would someone pull a prank like that and ruin the show for everyone? Looks like the boys have another mystery to solve!
