- Zowie!
- 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.
- Now, do something about those chattering teeth!
- Now, stop that! Don't be such a fraidy-cat. Come on!
- Hmm. I wonder what's inside this deck box.
- Look.
- Hey, there's a pair of shoes in here. And look what they're attached to!
- Zoinks!
- Hey, a full house! Gee, thanks a lo... Yikes!
