You grin at the Easter Bunny costume, a pale blue full body suit for a really little kid. Your mom picked it out for you when you were in kindergarten because it looked like the one in that movie with Ralphie and the BB gun. A Christmas Story. At least yours was not pink.
The costume is tiny now, though you remember it being a little baggy. Maybe you could pull the head piece on? You know you will look ridiculous, but no one else is here. You open the back up and push your head through, only to find that the neck opening is really tight. You are not worried about ripping the seams and force your head the rest of the way in. Despite being old, the fabric and thread must be really good, because nothing rips. Your head pops through, finally, but now the face opening has your jaw clamped shut like a vise. You wonder if you can get it off without ruining it.
Then something must have ripped or given way, because the pressure is relieved so suddenly you feel dizzy and sit down hard on the floor. Damn! The costume must have been cutting off blood to your brain! Your head clears after a minute, and you reach up to tug the costume head off - only to freeze when you discover your hand and arm are inside the fake-fur costume. Gasping, you look down and see that ALL of you is inside the costume! Where are your clothes? How could you have fit in this tiny outfit? That's when you notice the room looks a whole lot bigger than it did before.
