I take no credit for this other then thinking of an idea of having just skins for the vanilla monsters, so they are still the same old but with a new coat so to speak to add variety/flavor. I go the idea from seeing the work @mick87 (viewtopic.php?f=46&t=69289) and also the work @bLUEbYTE (viewtopic.php?f=46&t=66421&p=1125666).
So i combined their work and i think this turned out great, only bug i can't figure out and if someone can help is how to also get the original monsters to spawn along with the new skins.
