Description of feature
When the Symbiont walks around, it would be kinda cool if it changes the blocks below it into its respective tainted version (e.g. Grass Block into Tainted Grass Block). Or instead of that, since it would be crazy if you made a tainted version of every single block in the game, you could make something similar to snow or vines or that thin sculk thing or Idk whatever. It could also spread to like 3 or 4 blocks width. Idk it's just some goofy idea

I also wanted to suggest the WS spawning some new creatures similar to the "Druul"s from the movie Raya and the last dragon
but eh I don't think that would be cool anyhow (and I thought THESE things could leave behind a tainted trail or something Idk).

Well, Cracker will NOT add mobs that comes from another movie. So there will be a low chance of Druul. But, Cracker can add some sickened mobs that are in Minecraft.
