I feel like I got kinda lazy with Gokunmon here, but this Baby II Level Amphibian-type DigiFake IS just a bit, wide, pancake-flat baby with a bigass mouth. Its name is derived from the Japanese sound-effect for gulping or swallowing (which led me into some delightfully unexpectedly pornographic material when I was looking it up). As noted in the illustration’s notes, Gokunmon’s special is Big Gulp, where she just Kirbies the shit out of whatever poor fool is standing in front of her. She can’t swallow foes TOO much bigger than her, but her body can stretch to accommodate large targets and even if she can only gulp down a part of the foe’s body her body’s corrosive enzymes can dissolve part of their outer data layers, weakening their defenses.
Ah, right. She’s Gillmon’s evolved form, too.
