Arnie is a teen gambler from the episode,"Double Or Nothing."
While Fat Albert and The Gang are bowling, Arnie is first seen at the alley, playing at the pole table by Rudy. Without notice, Arnie is actually a pool shark who deceived Rudy into gambling by rounds of pole games. The Gang, especially Fat Albert warns Rudy that gambling is not good and will lead him into jail. Not listening to the advice he's been given, Rudy continued to gamble with Arnie and after betting some money, he informed the kids will get money as well if they join him and Arnie in a pole game but instead, to stop Rudy from losing everything from gambling.
Rudy then changes his ways and stopped another teen boy from getting tricked to gamble. Betrayed, Arnie and his gang chase after Rudy until The Gang scares them away.
