These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Spy Kids
Big Lipped Alligator Moment: The appearance of the "real Guy" (played by Elijah Wood) in the third movie. To clarify, he just suddenly shows up, gives an inspirational speech... then he gets severely curb-stomped, booting him out of the game. He is never talked about again.
Ham and Cheese: Sylvester Stallone as The Toymaker in the third movie. He is clearly having the time of his life as a madman evil video game programmer who talks to holograms of himself as a hippie, a general and a mad scientist. Him sporadically shouting his dialogue helps.
Toy Ship: Juni and Alexandra in the second film, and Juni and Demetra in the third film (with a Ship Tease of Juni and Gertie at the end, too). Carmen, who at least looked old enough to be interested in the opposite sex, only got an unreciprocated crush on Gary in the second film.
