I recently came across a post by Malcadon linking to a site that has some AD&D conversions for critter from the Herculoids cartoon. Love that show!
So I thought I'd share the link with you Old School folks that might not be aware of it!
Herculoids: The AD&D Files
Excellent fodder for your Gamma World, Planet Algol, Labyrinth Lord or Mutant Future Campaigns!
