SuperFix Progress

I have some ideas/suggestions.when a cow strikes a cow, make it a mooshroom cow and the block beneath it turns into mycelium. Make geodes spawn randomly in the end. Make snow spawn if the block below it is one block below the height limit. With the conditions to spawn hostile mobs, and a skeleton spawns on a snow block or snow, make it a one of those blue skeletons idk the name. Same with husks but for sand blocks which comes from wandering traders. Make foxes spawn near multiple berry bushes. Spawn cocobeans on jungle trees when you plant them. Wolves spawn in plains biome. Make salmon spawn in either one or two block deep water.
