What Could Have Been: Before May 24th, 2012, there were several potentially entertaining splices and running gags that had not been (respectively) played on the show yet and brought to their full potential. Trolls were looking forward to a long, fruitful, fruitbowl summer of Karaszkun splices and tiger shrimp-induced rages.
Not to mention that there were a lot of other subject matters that never had been used, such as the Petter fanbase which came into existence in November 2012. (and knowing Ghost his love for Bronies, he must love pets as well... right?)
