Oki Doki (Pee-wee's Playhouse)
Joey Miyashima played Oki Doki, Herman's pen pal from Tokyo, in the episode Accidental Playhouse.
Mrs. Rene gives Pee-wee a letter from his pen pal Oki Doki from Japan. In the letter, which Conky translates for Pee-wee (since he can't read Japanese yet), Oki tells Pee-wee he is coming to visit him. Oki shows Pee-wee sushi, origami, and Gamera.
'Pee-wee Herman, comedian Paul Reubens' signature character, is the titular protagonist of Pee-wee's Playhouse. He is the owner of the playhouse. He is a zany, childlike fellow with a pomaded crew-cut, a too-small gray suit, a bow-tie, a high, nasal voice, and a frenzied manner. His playhouse boasts oddball characters and talking furniture and he likes to ride his bike and cook, whipping up such delights as Ice Cream Soup.
