[...]

- What's going on around here?

- By your confusion, I deduce you're Darkwing Duck.

- I'll make this simple. This is your world. This is our world.

- You, Darkwing Duck, have traveled through the doorway that separates your world from ours and entered the Negaverse.

- Here, everything is the opposite of your universe. And Negaduck rules supreme.

- Oh, I get it. I fell into a big birthday cake, and now I'm in another universe.

- That's right!

- I don't think so.

- Tankard H. Muddlefoot, where are you?

- It's Mother and Father! Hide!

- Ooh, Tank, dear, you're missing Honker's birthday party.

- Lord Negaduck, what an honor. We didn't expect you to show up.
