Assemble the Team Edit
(It starts with a view at the Bikini Atoll Island, the camera then submerges underwater to the city of Bikini Bottom, then Conch Street.)
- French Narrator: Ah, Bikini Bottom. A paradise of the ocean floor. Home to many undersea creatures living their lives in peace and tranquility.
(SpongeBob then exits his pineapple home, happily and spots Gary at his path.)
- SpongeBob: Good morning, Gary. What are we gonna do today?
- Gary: Meow.
- SpongeBob: Great idea. Let's visit Patrick--
(SpongeBob was then suddenly interrupted by feedback, coming from a few yards from his house, from PA system hooked on to transportation machines, Jellyfish Harvesters, with mysterious fish controlling inside, attracting the other citizens.)
- Plankton: (amplified) Citizens of Bikini Bottom. May I have your attention, please?
- SpongeBob: I wonder what's going on?
- Gary: Meow.
- Plankton: (amplified) From now on, I, Plankton and the Syndicate, will rule Bikini Bottom. Hahahahahaha. But I'm fair. I listen to the little people; those of you who don't want me to rule, raise your hand. Get them!
(Plankton's machines start sucking up all the people, forcing SpongeBob to hide behind his pineapple with Gary)
- SpongeBob: Plankton can't do that to people. (gasps) Oh, no. If Plankton's in charge, he'll steal the Krabby Patty formula and shut down the Krusty Krab!
(Just then, a portal appears, which Jimmy's pet robot dog Goddard comes out of.)
- SpongeBob: Ahh! Don't eat me!
(Goddard's screen opens up showing a transmission from Jimmy Neutron)
- Jimmy: Hello, SpongeBob. We haven't met but believe me, I'm your friend. Plankton has joined forces with villains from other worlds. And with their help, he's taking over Bikini Bottom.
- SpongeBob: Come on, SpongeBob. Wake up. Oh, I must've had too much ice cream last night.
- Jimmy: I've been gathering the information about your world and I know you've dealt with him before. Please, SpongeBob, we need your help.
- Plankton: (amplified) Anyone else care to defy me?
- SpongeBob: Okay. I'll do what I can to help.
- Jimmy: Follow my dog and he will lead you to me. I'll be able to tell you more when you get to my lab.
(The transmission ends)
- SpongeBob: Gary! Stand guard and don't let them in. I'll be back soon.
- Gary: Meow.
(SpongeBob follows Goddard as they both head into the portal to Jimmy's lab.)
