Trials Of Derpulies is a modded Minecraft series uploaded to the main Yogscast channel. The series features 3 teams: Sjipos (Lewis, Sips, and Sjin), Hat Films (Ross, Trott, and Smith), and Flux Buddies (Duncan, Hannah, and Kim). The goal of the series is for the 3 teams to compete to win the challenges of Derpulies, a mighty king. The series ended with Derpulies going mad with power and turning on the teams, who eventually teamed together and killed him. The series was succeeded by the Trials Of Skobbels, which began on September 25, 2015 and recorded in mid September.
