Mr. Eugene H. Krabs
SpongeBob SquarePants/Gary/Mr. SquarePants/Narrator/Various Others
Squidward, SpongeBob, and Patrick are wearing their fishbowls upside-down during the scenes where they are in Sandy's treedome.
When Squidward drinks all the soda in order to produce a burp, he puts all the soda bottles next to his chair. But the many soda bottles are not seen in any of the next scenes.
When Squidward was first shown in Sandy's house, he had on a water helmet. However, when he is prepared for the procedure, he is no longer wearing the helmet, and he is not seen with it on for the rest of the time he is in Sandy's house.
How can Sandy smell Squidward's breath if she had her helmet on? She couldn't smell the sweaty guy from Karate Island, the odor didn't get into her helmet.
(inside the submarine while still inside Squidward)
SpongeBob: Reporting for duty, Mr. Krabs.
Patrick: (flush sound) Squidward! The toilet's backed up again!
Sandy: If you can make a big enough burp...
Patrick: We can filter the CO2 through out ballast tanks, refire the engines, and ride the shockwave out of here.
Sandy: He's right.
Sandy: We're going through with your plan, Patrick!
Patrick: What plan?
(Sandy smells Squidward's breath after he burps)
Sandy: Pww! What have you been eating?
Sandy: Mission accomplished, fellas. Now all you have to do is...
(Squidward knocks her away from the microphone)
Squidward: Get out of my body! GO!
Patrick: (sees Grow button) Grow? (pushes the grow button)
(SpongeBob, Sandy, & Squidward scream)
Patrick: (sees the "shrink" button) Shrink? I do have a lot of issues.
Sandy: Hey, what's that?!
Squidward: What? (looks other way while Sandy karate chops him in the head and he falls asleep)
Sandy: Sweet dreams, partner.
Sandy: SpongeBob! Patrick! Can you hear me?
Patrick: Sandy's in there? I'll save you Sandy! (grabs an axe and starts hitting the speaker)
Sandy: You itty bitty idiot!
SpongeBob: Sandy! Where are you? Where are WE?
Sandy: I'll tell y'all where you are. You're trespassing in my lab. You're trespassing in my submarine. And, most of all, you're trespassing in Squidward's body!
Patrick: I thought this place was a dump.
Squidward: I heard that!
Patrick: Hey, SpongeBob.
SpongeBob: Hello, Citizen.
Patrick: What'cha doing?
SpongeBob: Guarding Sandy's submarine.
Patrick: Wow. I've never seen a real submarine. Can we go inside?
SpongeBob: Can't, I'm guarding it.
Patrick: Oh, man! Can't you guard it from inside?
SpongeBob: You're right! Patrick, you're a genius! (starts bowing down to Patrick)
Sandy: (in a giant voice) Patrick! SpongeBob!
Patrick: Oh, no! Sandy grew to gigantic size!
SpongeBob: I don't think Sandy grew, Patrick! I think we shrunk!
Patrick: Silly! Don't you think it's more likely that the whole entire world grew?
Sandy: This sub is approximately seventeen times harder to drive than a boatmobile... which you haven't successfully mastered yet. So, just take it nice and easy.
SpongeBob: Nice... and... EASY!!! (starts driving the sub like a maniac)
Years after this episode aired, Miriam Starobin, a viewer from New York, saved the life of Allyson Golden by performing the Heimlich Maneuver. Starobin saw Golden choke on a piece of gum after hearing a joke. Starobin explain she remembers SpongeBob doing the same thing to Squidward, after he choked on his clarinet.
There was a mistake in the DVD description of this episode. It said SpongeBob, Patrick, and SANDY go inside Squidward to retrieve the reed. Sandy didn't even touch the submarine.
Plankton does not appear in this episode.
We learn that Sandy's submarine is seventeen times harder than driving a boat mobile.
Mr. Krabs makes a cameo appearance at the end of this episode.
This is the first time SpongeBob and Patrick drive a submarine.
This is the first time Squidward goes inside Sandy's treedome.
The first time Squidward is seen wearing a water helmet.
Fifth time Patrick said something intelligent. The first time was in "I'm With Stupid," the second time was in "The Secret Box," the third was in "Patrick SmartPants," and the fourth time was in "Once Bitten."
This episode premiered along with a rerun of the episode, "All That Glitters."
Patrick: AAAAAGGHH!!! Sandy grew to gigantic size!
SpongeBob: No Patrick, I think we grew smaller
This is a similar to a quote said by SpongeBob and Patrick in the episode "Mermaid Man and Barnacle Boy IV".
The episode is a spoof on the 1966 film: Fantastic Voyage, but can also be considered a spoof of the song "Fantastic Voyage" by Lakeside or the song of the same name by Coolio.
