History
The world appears to be a parallel Earth where it's been ruined by a series of nuclear explosions. But the humans remain completely optimistic that things will turn out alright in the end. It is referred to by Howard the Duck as a Don't-Worry-Be-Happyverse.
Notes
- The name comes from the often quoted "don't worry" and "be happy".
- "Don't Worry, Be Happy" is also the name of a song by Bobby McFerrin.
