"Louie's Lethal Lilac Time"
Louie the Lilac returns, this time intent on cornering Gotham's fragrance market. He steals a large chunk of ambergreas from Dick Grayson and his friends while at Bruce's beach house. Then he takes the two of them hostage so they will surgically remove scent pouches from some animals he stole from the zoo.
Bruce and Barbara chaperone Dick's party at the beach house. Seeing Dick and his friends returning from the beach, Bruce remarks, "We'd better get the hot dogs ready."
