So, I could find no vector of the mysterious box anywhere. There was one low-resolution one without an SVG file attached, and it was kinda strangely interpolated, so I decided to make my own.

This box is actually mysterious for two reasons. For once the obvious one, that nopony knows the contents yet. The other reason is that no vector artist (except the maker of the show) has any clue how the box looks on the bottom. I could surely have been lazy and just vector it together with the flower, but that’s clearly cheating. So I tried a few things and decided that this could probably be the correct design. I actually wonder if we will ever find out for sure, as Hasbro could keep the box in the flower forever.
