Pee-wee's Playhouse S02 E09 Playhouse In Outer Space

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.
