Microphone (or "Mic" for short) is a Toy shark creature (dog?) that Ez's parents bought from the toy store for Ez's 13th birthday! It's unknown what species it is but we know that it is a toy, therefore it is man-made and created in a factory.
Mic is created completely out of plastic. He has shiny holographic hair and a pair of bunny ears and antennae. There is a cone protruding out from the back of his head; it's probably supposed to be his shark fin? On his left hind leg, Mic is wearing one of Ez's leg warmers. Mic's right fore leg is bare (its plastic cover got melted or something) so Ez used a pink pillowcase to cover his arm innards. The only article of clothing you can take off of Mic is his shorts. Under it you can see Ez covered Mic's butt with stickers, and that his hiney has a pink see through window that lets you see his butt work (like those translucent Gameboy casings)
Microphone's tail is detachable, or is it? Mic seems to look a little panicked when it falls off (his face goes like 0_0 which is the only other facial expression he makes) as if that wasn't supposed to happen..? We can also observe that his eyes are two different colors
Microphone is sentient and has the ability to make decisions on its own! But it doesn't seem to be that intelligent. It seems that its only goal and purpose in life is to take care of its owner, Ez. It doesn't talk at all and its default RBF (resting face) is a n⎵n
