An Insane High School Surprise

An Insane High School Surprise is an upcoming 2025 American direct-to-video adult computer-animated musical comedy-drama adventure film. It serves as a bridge between the sequel and the third film and the bridge between High Schoolers 2 and its sequel. It is a crossover between Sausage Party, Annoying Orange, South Park, and High Schoolers.
This is the first film to replace the main four of Royal Mothers with their toddler counterparts, and the first and only time the protagonist of The South Park Parents and Friends Show became a puppet.
