Awesome 3-D art, and very creative! 5/5'd! And to kirby rules 101: If you look on the side of the box, you see the DeDeDe brand. I think you can figure out the rest.
Explosive Kirby, haven't you seen that Kirby 64 cut scene with Waddle Dee eating? Clearly, it shows that waddle dees eat by employing a modified process of concentrated molecular diffusion. Also, a waddle dee is on the box because the item is a common, nondescript item as the waddle dee is a commonplace enemy. The box is targeting the ordinary citizens of Dreamland.
