This episode 9 is kind of different for me. Maybe because I'm not that kind of beach girl, so, I don't enjoy surfing and all. But the episode is funny. And also, I love to see Scooby-Doo's clever. I've never seen Scooby saves someone rather than Shaggy. So, I said it's different from the other episodes I've seen. But I don't understand the reason that much. Still, it's OK, and hence, it's a fine episode. I can't wait to see more and next episodes.
