"Handwriting on the Wall."
The gang first noticed graffiti on the walls of the fence everywhere then throughout the town. Later on, The school's field trip was cancelled due to not enough money for the field trip so the gang decided to get rid of the graffiti themselves. After painting over the graffiti, The gang caught Marlin, who appeared to be the one writing all over the walls and fences. The kids held a play, written by Marlin, to earn money for the field trip. Marlin appears on stage at the end of the play and bows in honor for credit he included and reforms.
