S4E19 Gary and Wyatt's Bloodsucking Adventure

Gary, Wyatt, and Lisa choose to hit the club after dark, embracing their inner "creatures of the night." Lisa transforms them into stylish vampires, but with a quirky twist—they crave Yoo-Hoo instead of blood. With their new vampiric powers, the guys discover they can hypnotize people, which they eagerly test out on attractive women. However, their fun takes a turn for the worse when they encounter a genuine pack of bloodthirsty vampires. Meanwhile, Principal Scampi and Chett are on a mission to thwart the real vampires and take on the role of vampire hunters.
