Ugrakk

The Ugrakks were a humanoid species of fungus, which resembled bipedal, blue elephants. They had power over other fungi on their world and could secret deadly spores. Their natural enemies were the Zama flies.

They possessed sufficient technological abilities to bring the Doctor's TARDIS to them from quite far away. However, they were not able to leave their planet themselves and so kidnapped the Doctor to assist them, as their world was dying. The species presumably met its end after a hive of Zama were released underneath their city. (TVA: The Ugrakks)
