- Yeah. All that's left are her footprints on that rug.

- Wait a minute. There's something funny about those footprints. Look at the way they slide back to the edge of the rug.

- That can only mean one thing.

- Like, she had big feet?

- No, silly. She slid down through a trap door in the floor.

- So that's how it works!

- Yeah, but then what happened to Daphne?

- I don't know.

- Shaggy, footprints.

- Footprints? Look what Scooby found!

- I wonder where they go.

- Let's follow them. Maybe they can lead us to the answer. Come on!

- Zowie!

- Look at that!

- It's an old derelict riverboat.

- And those footprints lead right to it.

- Look! Look! It's the zombie's boat!

- And get a load of that boat pole.

- Like, it's got a kooky metal tip on it.

- I wonder what the tip is used for.

- For more than just pushing that boat around, I bet.

- Come on! Let's go aboard and hope we can find Daphne.

- Every time we split up, it's, like, I'm stuck with you.
