Pee-wee's Playhouse
Playhouse In Outer Space (2x9)
:
Aaaaugh! The secret word is "zyzzybalubah," and that can only mean one thing! The entire Playhouse, including Reba, is sucked into space, transported to a strange planet, and taken over by an odd, lonely alien! Yvona, an alien from the planet, is trying to escape the unfriendly Zyzzybalubah, but Pee-wee teaches him how to be polite and make friends. Reba teaches Pee-wee how to whistle, and she sings a song.
