Iggy and Curly are thrown into trash cans right away. However, they are seen with a few other 4th graders escaping through the front door and they aren't covered in garbage.
When Arnold's class is watching the clock, Nadine's hair is brown. In addition, Mr. Simmons' face is much darker than it usually is.
Stinky appears in Park’s safehouse even though he hid in a trash can at the school.
Also, he appeared in the streets trash can at the end but at the start of the 5th graders canning he hid in the schools.
Also, when the kids are seen running out of the school for a brief second you can see Eugene even though he appears to be inside the school in the next shot.
Before Wolfgang trashes Arnold and Gerald, they re-appear laying on the wooden dolly in another shot, even though they've already stepped off.
After being put in a trash can and rolled down the hill, Arnold gets out and says, "you know, that wasn't as bad as I thought it would be". This is somewhat inconsistent because Arnold and Gerald have both already been in trash cans before this episode. Arnold in "Stoop Kid" and Gerald in "Gerald's Secret". Though he could be referring to being put into a trash can and rolled down a hill as opposed to just being in a trash can...
The tradition was putting all 4th graders in trash cans. However, despite we seen some girls like Helga, Nadine, and Phoebe run away, we never seen any other fourth grade girls getting thrown in trash cans only the males.
It is currently unknown if Wolfgang and his friends ever got suspended or thrown into detention for harassing fourth graders and putting them in trash cans.
