I was wondering if anyone remembers these Lucky Charms commercials. I saw them when I was 4 or 5 (c. 1984) and although I watched them on a black and white TV, was charmed. I loved rainbows. In the first one, Lucky, in his constant attempts to run away from chasing kids, blasted off into space in a little spaceship, IIRC. Then this big, flying saucer-shaped object with eyes opened a mouth-shaped hatch and Lucky had to escape back to Earth and to the kids. Note - it's NOT this later one:

(I'm not confusing the big seashell with the spaceship, this is a later commercial - maybe it was based on it, though).

In the other one, as I recall it, Lucky ran up a rainbow carpet that formed a stairway. The kids pulled the carpet and he fell down.

Any of this ring a bell?
