Goof: The group's music instruments and luggage are on top of the van. But in the overhead shots during the chase scene, they're missing and are gone after they left in a taxicab with no indication they took it with them considering they needed to get away quickly.
Goof: When Valerie is packing a bathtub into one of the crates, her left hand is a pale complexion.
Goof: When the Laser turns on his viewscreen to observe the gang training his men, the first image seen is Josie with Alexander when the latter says "OK class, observe carefully" as he's holding a pole with a plunger. However, he's speaking with Alan's voice just before the actual scene switches to Alan holding a lasso with Melody, Josie, and Alexander in the background.
Goof: When Josie notices the Laser's machine is doing everything the opposite way, Alexander's collar is colored green instead of orange.
(The gang prepare to deliver themselves to the World Scientist Foundation in a pair of crates)
Alan: These labels will do the job. Are we all set?
Alexandra: No! The crates are packed wrongly. (She pulls Alan into the crate with Alexander, Sebastian and herself)
Alexandra: Now they're packed right! (Closes her crate as the girls do the same with theirs)
Josie: When the Laser opens those crates, we'll be in a real pickle.
Alan: Then I guess the only way to get out of that pickle is to get into that complex.
Alexander: (Repeatedly hitting his hands on his ears) I-I-I gotta retune my ears. It sounded like he said "Go into that complex".
Alexandra: He did, chicken brother!
Laser: Strange, I've never heard of QUACK. But you did manage to break into my complex
Alexander: Oh, like this was a real nothing for us superspies. Not like the time we borrowed a secret nuclear sub, of course surrounded by a thousand guards. Or the escapade where we kidnapped the Atlantic Ocean and held it for ransom. Or even...
Alexandra: (Shuts his mouth) Don't overdo it you loudmouth!
Laser: Very impressive! I insist that you teach us your methods.
Melody: Oh, goody!
Josie: Oh, golly! Now we're in a real mess!
Alexandra: (Whispering) One of these days, I'm gonna put a zipper on your lip! (Alexander gulps in fear)
Alexandra: You plungerhead, get me down from here!
Alexander: Now what'll I do?
Alan: Start climbing!
Alexander: But when I get up there, she'll clobber me!
Alan: If you don't, they'll get wise and finish us.
Alexander: (Climbing the rope) Ooooh...Either way I'll lose.
(After Alexandra's plan to sabotage Josie backfires causing her to spin on the turntable)
Music Director: Hey, that was a great new sound, kid! Do it again and we'll record it as the "Ooh, Ow, Ooh" song.
Alexandra: How would you like to record a "Fat Lip" song?
Alexander: Tsk, Tsk...My sister's big chance to cut a hit record and she chickens out. (Everyone else laughs while she stands there angry)
Song: It's Alright with Me.
The gang try to trick the Laser by making him think they're part of a made up organization called QUACK, Quality Undercover Agents Checking Kooks.
