 In "Five Gold Rings", he leaves school to become a police cadet, and arrests Del and Jumbo for selling illegal American records (although he is snubbed by his sergeant, who goes on to keep the records for himself and lets Del and Jumbo go with a warning).This is the last time Slater is seen, as he does not appear in "The Frog and the Pussycat".In the entire series, Slater is the only character portrayed by an Academy Award-winning actor.
