Continuity mistake: When Sharkboy and Lavagirl burst into the classroom looking for Max, there is writing on the blackboard ("Science, Chapter Two") written in yellow chalk. Strangely, later in the scene the writing is now written in white chalk, and the handwriting of the text is noticeably different. Then, later it goes back to yellow! (00:16:45 - 00:17:40)
Revealing mistake: When Lavagirl burns the diary, it goes up in flames. However, if you watch Max and Sharkboy, they look at an unseen object falling to the ground. The unseen object is the diary, taken out in editing. Later, Max looks back at the diary on the ground.
Mr. Electricidad: OK, kids, who's next? Remember, there are no dumb ideas.
Linus: Maybe we can freeze his circuits.
Mr. Electricidad: That's the dumbest idea I've ever heard. We're in the middle of Texas in August.
Trivia: The music when they first fight Mr. Electric is the exact same as the music as the Mario bowser fight.
