They Came from Aargh!
Cricket Magazine Vol 10, Num 3, Nov 1982
Turning three chairs into a spaceship, three kids become Blob, Blub, and Bleep, space explorers who have come to earth in search of chocolate cake. Unfortunately the dreaded mummosaurus makes them eat cheese omelets before chocolate cake. In the end she kisses them good-bye and wishes them well in the space travels.
