Secret Valley(1982)

Secret Valley is a children's series set at a holiday camp built in the fictional Australian town of Bildarra, converted from an abandoned ghost town into a bustling resort. Young campers and staff regularly clash with Spider McGlurk and his gang from nearby Spider Cave in playful but chaotic battles. Armed with flour bombs and food-based weapons, both sides wage war that inevitably leaves everyone covered in mess. The show combines adventure, comedy, and the spirit of summer camp mischief, following the campers as they navigate friendships, challenges, and their ongoing rivalry with Spider's troublemaking crew.
