Pokécraft is a Pokémon inspired texture pack. It is especially the terrain that got a very similar look to what you would see in Pokémon, but also animals will give you reminders of how it looks whenever you come across them.
This is a very old texture pack. If you found this post you were probably looking for the PokéCraft mod. You can find it here: http://mcpedl.com/pokecraft-mod/
