Difficulty: Easy

Bobby is scuba-diving with his buddy, Nobby. They are exploring the Great Barrier Reef off the coast of Australia. All of a sudden, a big eel jumps out from behind a rock and swims right between Bobby and Nobby. Both of them are a little startled, but the eel swims away and they are both left unharmed. Bobby turns to his friend and gives him the “ok” signal with his fingers. His buddy then gives Bobby the “thumbs up” signal. What do they do next?
