A Miniature Circus Tent

I pushed past the hem of the sofa throw and found a curious striped relic lying flat on the floor: a red-and-white popcorn box, folded completely flat! The bold jagged stripes screamed spooky carnival dread. Naturally, every sinister arena demands a centerpiece. I braced my paws against the slick cardboard and shoved my snout straight into the flat seam. With a crisp pop, the sides expanded, snapping open into an upright, four-cornered tower right on the hardwood! Now the eerie circus grounds finally have a grand pavilion standing proud.
