Yeah. Sorry about the little bugger on the screen, but he's annoying enough to be one of the more prominent characters.
Woe Is Me.

MANY doodles, A lengthy doc made three years ago that I still update time to time, and multiple "what-ifs," like a puppet.

Gef D. Mongoose is Phone-Dude's friend of 15 years. Gef came with the house, and though he'd shut up for weeks, he never left the poor man alone.
When he first moved in, Gef promised him good luck. He thinks he has the opposite, but he seriously should not be alive at all. Funny how his luck works.
If you could imagine, an annoying and disruptive talking animal wasn't (and still isn't) the best assistant for trying to figure Everything [aliens] out. Phoney didn't really care for Gef's antics, but if he's going to connect anomalies to other anomalies, why not include the one in his house?
He concluded that Gef is a "[magical] talking animal." He isn't sure how magical his buddy is, but he's right.

All this guy does is talk and throw stuff at people. He is 6 to 9 inches long with dark blue eyes and human-like teeth. He seems to not like that, because he almost never shows them. Recently, he figured out what a crab cake is.
Fits the 'small feisty animal' trope; think of a less annoying Scrappy Doo. He can be very mean, though he isn't truly "Evil."
He is afraid of ghosts, and if he's really scared of you he'll believe you are one, or maybe even a demon.
Likes reading tabloid and bible verses (Phone-Dude has neither of these in his house and hates the former.)

Has a [NOT CURRENTLY CANON] bigger form. It's a huge and aggressive animal with two false eyes that can produce mist.
