What if there were new types of evolution revolving around symbiotic relationships, like mutualism and parasitism? These could feature new Pokemon, like a bird species and a tree species that merge in final evolution to feature a tree with a nest or some shit?

Idk, just a thought. It could be really neat to see Sudowoodo or some shit with a Sparrow nest in his branches. It would be a new way to do evolution, like they both have to reach a certain level while in your party to merge-evolve or whatever.

Anyway, other ideas?
