Gen 2: Mudkip: Speeds up the growth of mushrooms and his big radius changes cows into mushrooms Treeko: Collects apples from trees Kyogre: Produces water buckets Groudon: Produces lava buckets Arceus: Produces 1 nether star per 1 hr Snorlax: Gives you an inventory space of a double chest
I like your ideas for Skyblock they sound useful and creative. The one thing i disagree on is having Arceus because he is not in the server yet so it wouldn't make sense to have him in Skyblock but not Pokeworld also he is in a different gen and the server just updated to Gen 3.
Great suggestion although some of the pokemons need some adjustments and changes.For example Kyogre doesn't do something really important since you can make an infinite water source and the snorlax can be easily used for an automated chest absorber.
