Jacob Two-Two Meets the Hooded Fang (1978)

Kids Beware!

Nobody ever listens to Jacob, so he always has to repeat himself. A trip to the grocery store leads to a misunderstanding and Jacob falls asleep hiding in a park. When he wakes up, he discovers that he is in trouble for insulting the store clerk. He is sent to a prison for children that is located on Slimer's Island and is run by the Hooded Fang, an ex-wrestler who outwardly hates children. Meanwhile, Child Power representatives the Intrepid Shapiro and Fearless O'Toole try to find the prison's hidden location to help free the children.
