"Heeeey, Masterrrr~"
You look up as a yellow ringed, furry black head pops through the doorway into your room, where you rest on your bed. "Yes, Umbreon?" You say, knowing the probable outcome of this scenario. She walks over to your bed and sits in front of it, staring up at your feet. "You know, your bed is awfully big. Much bigger than you. It'd be a shame to leave all that extra space unused." She wiggles her sleek furred butt, and hops onto the bed with you. She then pats down the bed, pushing the blanket flat as she stares directly at you. "You'd better be grateful. Anyone else would've just left this spread empty, not me. This bed's getting filled today, no chance of sad mattresses here." You ignore her statement, laying your head back onto the pillow and closing your eyes, gazing into darkness. Then, you feel a pressure on your stomach. "Actually, your fat belly's a better place to sleep, don't you dare roll onto me, or I'll let you have it." You continue to keep your eyes shut. "Love you too, Umbreon." Nothing in reply, but a foreign force flumping down on your midsection, giving you a loving gaze before shutting her eyes as well. Your sleep was oddly dreamless, making the loss of air more pronounced as you wake up, pushing out and swerving your head for a pocket of oxygen! You try to shout for help but are muffled by many mouthfuls of soft substance! "Mmmm! MfHHHH!" You attempt to claw your way away from the surface covering your face, but it seems to be everywhere, extending like a soft rug...
"Mmmmmm..."
A sleepy moan rattles through your body, then the choking black matter all falls back at once as the weight on top of it rolls over. You sputter and scramble away from the giant... thing as quick as you can, pushing up the softer covers of this new unknown world as you head towards the nearest light you see. Within seconds you burst out into the moonlight, pouring in through the nearest window and revealing your own covers, now large enough to cover up a giant!
This is your room, you've somehow been shrunk down in your own room! And if this is your own room then... Umbreon must be somewhere around here!
You look around and...
