Detention Adventure: Season 3, Episode 4

3 - 4: Ode to Joy

The gang tries to crack the illuminated code of the train platform contraption, but they use up another precious fuse with each failed attempt. Joy and Dash have proven themselves the best at the puzzle, so they decide to stay in the woods to keep trying to solve the riddle. Meanwhile, Brett, Hulk, and Raign build a Dummy Joy from a CPR mannequin and manipulate it to give the impression that Joy is still with the gang in an attempt to trick the teachers.
