[...]

- Dracula and the Monster are out to get you and me because your uncle wants you to succeed him.

- Well, I've thought about that, and I just can't do it... whether my uncle likes it or not. I'll just tell them that.

- They won't listen to you or your uncle now. They've already gone too far.

- Besides, something much more horrible and deadly will be threatening this island soon.

- What?

- Never mind.

- We've got to leave here now.

- Without even saying good-bye to anyone?

- Felix, I've a boat hidden at the other end of the island to help us escape. You must come now.

- Oh, what have I done?

- And so I say, brother monsters, unless we can stop Felix Flanken from succeeding the Baron, then our organization is doomed!

- Yes, Yetch?
