I have made all kinds of plushies and never did I see one (especially a 3 clothed one) always in the 120 range. Maybe it was a red one though.... which I tend to avoid. Were you told by an OLD PT player? I may have to check your story out with my own testing.... lol
Blue Draiks tend to selling between 94-125, but the price changes so much, it's just frustrating to try to make and sell them. They usually run about 50 nps cheaper to build than the Orgins. If you really were determined, make a butt load of them and just ship one here and there, wait 5 mins and see the prices, if they are around 110, ship a bunch to the store.
You really don't want the prices to be over 110 unless you just don't care how long it takes to sell them. For 100 sized jobs, it could take up to 7 updates. Imagine if the size was 500 or even 2000, it would take FOREVER.
The main plushie to build here are Yellow Orgins. If you do any other, you're just playing around at that point. Yellow Orgins will give you the trophy/avatar that you need. Once your get the cool things, then maybe you can experiment finding that 120 plushies (if it exists )
