As you poke your head into the den, the Pichus within squeak, and scurry to the back of the den. It widens out underground, so you slink inside and almost casually reach out with your forepaw, pulling a squealing 'chu towards you. Your rough tongue licks over it's face, made a bit salty by tears, and then, your jaws open wide, taking the Pichu's head inside. Its squirms intensify, but it's of no use. You toss your head into the air, opening your jaws a bit, quickly snapping up its tiny body. Then, your tongue curls out again, pushing the feet in. Your neck bulges as you swallow, the Pichu squirming even as it comes to rest in your now-sagging belly. One of its siblings suddenly tries to dash by you, but your paw comes down on its tail, and it falls flat on its face. You then lean your head down, and take the tail into your mouth, slowly sucking the 'chu in tail-first. And soon, your belly sags even more, almost touching the ground. The remaining two quiver in the corner as you pad closer, licking your lips, hunger still in your eyes...
Not long after, you flop onto your side, one paw resting on your gorged gut, purring in pleasure. You are now the sole occupant of the den, and the squirms in your belly are reduced to mere twitches as oxygen deprivation and acids begin to take their toll. After a few moments, you sit up and yawn, your belly audibly gurgling as it works feverishly on your meal.
With the unfortunate Pichus now reduced to an unrecognizable mush inside you, you stand up, stretch, and poke your head out of the den. You catch the scent of a Pikachu and a, probably newly evolved, Raichu approaching, and quickly leave, heading into the bushes again. You hear anguished squeals soon after as the parents find their now-empty den, but they are no longer your concern, as you make your way quickly back to your own den. It's a hollow under the roots of a large tree, and you've dug even deeper, making a nice, wide spot for you to sleep in. And you proceed to use it for just that purpose.
