Ash's Appendix Surgery is the 63rd episode of Weekenders Adventures Chronicles.
After having a practice battle with Brock, Ash suddenly starts to feel pain in his abdomen. But when he goes rock-climbing with Mordecai and Rigby, the pain grew worse. Everyone realizes that the reason why Ash is having so much pain is because he has appendicitis. In order to save Ash, they decide to have him go through surgery.
