The Wegian is a diminituive creature that almost resembles a small or medium sized dog. The Wegian appears to have a scaled back, a piranha like mouth and clawed feet. It appears in the second Spore expansion pack, Galactic Adventures.
The Wegian appears in the adventure called "It Came From the Sky", in which the player's creature goes to a research station on an icy world to inspect a crashed spaceship. It appears to be the station's guard dog, and it happily follows the player as he moves about the base. However, when hostile infected researchers appered, the Wegian did not attack. This was probably because he knew that they were his masters, and didn't want to hurt him.
