The Tunneling Enderswarmer, as the name suggests, likes to spend most of its time underground. As with most Enderswarmer species, they live in colonies and are highly territorial; but one thing they don't share with most other species is their lack of wings, likely because they evolved to live deep underground instead of in the skies. This species is still quite new to our world, only a couple of generations in, so they're mostly found near the End Portals.
