When I was young I remember watching a cartoon movie, but I only remember bits and pieces of it. One of the scenes that pops in my head is something/someone running after a runaway (egg?), and a different sceen with a two headed snake or worm singing a song "Two Heads are better than one". Am I completely imagining it or is there a movie out there that I did indeed watch?:confused:

Gallavants (1984) (http://www.imdb.com/title/tt0272101/)
It's Gallavants
