Zero percent chance she got the one approved where they go inside Arnold. Everything is wrong with that field trip as a premise (including, ironically, that there's a brief scene where Arnold is seated on the bus currently inside of him).

We're singling out your son to leave behind such that I can have his classmates travel inside his body without his consent or even knowledge. All of this will be in service of a 3rd-grade biology lesson for which a billion effectively identical substitutes are available, including endoscopy footage that already exists. This will be monitored externally by our class lizard.

Arnold’s parents: “A bus full of kids did fucking what?!

Also, I didn’t know carrots could do that…”

"look I'm worried about it too, but when I go over there after school they're all grinning ear to ear. except that one kid."
