The Existence of Bigfoot is taken for granted throughout the greater North American continent, and so is his psychic abilities.

I think we’d all like to see him before we make that Magical Mystery Tour somewhere. 

Bigfoot knows when you are approaching  him, and he chooses to who he makes an appearance. His psychic powers account for this ability.
Remember, you don’t look for Bigfoot; he’ll look for you.

You’ve got to get a deal going. Keep you halfway, you know?
Have a meeting when you get up there. Sit in the room.
Wait for the appearance of Bigfoot. Dog Man. Lizard Man. Mothman. All of ’em.
Let them fill the room up. Every orifice.

OK, is he possibly an alien entity?
