Ryan: Are you alright?
Spongebob: Yeah, and you are?
Ryan: I'm Ryan. And these are my friends. Matau, Crash, Bertram, Sonata, Adagio, Aria, Sci-Ryan, Evil Ryan, Evil Anna and Spikewave.
Spongebob: And I'm Spongebob. Welcome to Bikini Bottom.
Spikewave: Cool. Are there any Heartless in this area?
Spongebob: I don't know what a Heartless is, but no.
Ryan: So why are in a hurry?
Spongebob: Oh yeah, I am late at the Krusty Krab! And I have to be there!
Ryan: So we take you there?
Spongebob: Yeah, come on!

Kaos: Yes. I think she is a princess.
Plankton: Why would she be a Princess?
Kaos: Belle from her world has taken.
Plankton: If you want her, then fine. After I give it to you, you summon all of your Heartless to bring me the Formula.
