Ecto Doge is the Floating variant of Doge, and it is two times more powerful in terms of health and damage. It's still a very weak enemy, though.

16 damage (10 DPS)
110 (single target)
26f (45f attack frequency)
6f (13f backswing)
Ecto Doge makes a cameo in a spinoff game called "GO! GO! Pogo Cat!", along with Pigeon de Sable and Brollow. It is the latest occurring of the three, and can only be seen drifting through the background after the twentieth checkpoint is reached.
Ecto Doge, Ecto Snache and Ecto Baa Baa are the only enemies to appear in Stories of Legend that do not appear in the Enemy Guide.
