The List/Haunted Train - S1-E8

Question: Why did that boy steal Arnold's ball? Was that the whole reason he came to the park? He seemed awfully obnoxious and destined to ruin Arnold's day, just wanting more clarity. Thank you.

Answer: The episode doesn't really elaborate on who the kid was and what his motives were, so its pure speculation as to why he took it. Perhaps the kid could simply want a ball all for himself and decided to just take it, or was simply a rotten kid. The truth is the kid's motives are not important to the story other than it highlights Arnold was having a lot of trouble getting through the list.
