Bob and the team are rebuilding an old shack on the beach and transforming it into a surf school. Brad Rad, the awesome new surf instructor is there to help. Meanwhile, Scoop, Dizzy and Scrambler are playing a game of monster chase. At the beach Brad notices that one of his floats has gone missing and the school can't open until the missing float is found. Bob and the team say they'll keep an eye out for it as they work on the build. As the build progresses, Scoop, Dizzy and Scrambler take turns to be the monster. But every time they whiz past, screaming with excitement, Lofty closes his eyes tight. Bob and Wendy reassure Lofty that there's no such thing as monsters. However, when Brad Rad emerges from the water in his diver's mask and snorkel, Scoop, Dizzy and Scrambler think he's a real monster! But this time it's Lofty who keeps his cool - there's no such things as monsters - remember! And by keeping his eyes open, he spots something else too - the missing float! Air Date: Apr 21, 2010
