So, in the pilot, guy with ice cream factory is trying to blow it up. It's also revealed that he's making mind-controlling ice cream... why are they trying to prevent him from destroying the factory?
"The Mayan Ice Cream Caper" expands on the pilot episode and reveals that it was a case of Nice Job Breaking It, Hero!. It probably didn't help that Horace was under the influence of the mind control ice cream.
Why would anyone even air this show? It's almost as if they wanted a repeat of Electric Soldier Porygon.
