Yep. But now we see that this "demon" has been the dog, Lenny, the yellow eyed fat guy, and probably the angry kid cartoon too. Not really a Mojo thing. Nor am I aware of Mojo doing telepathic bullshits on this level.
Very much Shadow King. I ever recall one seen where the blobby version had a shadow aura around him (late episode 2 memory thing). And of course, devil dog is named King. If it isn't SK, then they are throwing a lot of misdirection our way.
