About this Mod

By popular demand, this is a reupload of my RocketMons addon which I originally uploaded on curseforge (Original post).

This is an addon which includes a fully animated and fully textured model of Celesteela. I might also add other pokémon in the future if there's interest.

Currently, Celesteela can be found if you build a proper landing strip at very high altitude (300+ blocks) in certain hot biomes.
