Does anybody remember Pod on the BBC micro - probably mid 1980s? It was an orange "person" (i.e. circle with limbs and a face) to which you could issue simple instructions – typically one-word verbs. It could do most things you could think of (or at least, that I could think of as a 6-year-old), including "explode".
I have no particular reason for asking, other than nostalgia. I've tried a few searches but have been unable to find anything.
