S04E01 The Secret Snake Club

Billy, Mandy, and Irwin are on a quest to find the right club at school. Irwin hopes to join the Macrame Society to impress girls, while Billy shows interest in the Junior CIA Society but is unexpectedly coerced into joining. Meanwhile, Mandy opts for the "Secret Snake Society," which is run by three eccentric nerds. They unveil their plot to bring back Shnissugah, an ancient giant snake from Canada, to seek vengeance on the popular kids, but they lack access to Underworld powers. Mandy enlists Grim, who uses the internet to resurrect Shnissugah. Billy, acting as a junior CIA agent, thwarts Irwin's selfish scheme with the Macrame Society. In the end, Shnissugah turns out to be a harmless, tiny snake measuring only 8 cm (3.14 in).
