From Pixelmon Wiki
Unlike in the Pokémon games, Pixelmon does not use the "random encounter" method (e.g., tall grass, caves) for encountering Pokémon. Instead, Pokémon spawn naturally in Overworld, and a player can engage these wild Pokémon in battle. By default, normal Minecraft mobs are disabled and do not spawn when Pixelmon is installed, although they can be enabled by editing Pixelmon's config file.
