No, the plushie is tiny and squishy. Definitely nothing in it.
I even magnet-checked the mess of packaging with another magnet i have, and nothing.
Got the email back from the seller. Heh.
"I carefully look at the project packaging video; and post office bills weight 350 grams are consistent; This proof of the project intact; magnet in the cyst; now the only project is lost in the post office; I hope you as soon as possible to the local post office advice and accountability;"
Tho I do admit it will be amusing when the P.O. folks see the package. The styrofoam has broken down at the aggregate level and all the little styro-pebbles cling to everything.
