Joey: Hey! As soon as it stops raining we have got to go snorkeling! Some kid told me about the sea turtle and, if you blow bubbles in its face, it chases ya!

Joey: Oh... oh, but that's ok, I'll find someone else to do it... I'll do it alone, but... I don't know what happens if the sea turtle catches you...
