Parts 1. Here we have the majority of the small parts. The Unicorn Horns are pretty interesting and should make for excellent greebles.
Parts 2. These are the larger pieces. Those hinged jaw pieces in the upper left look interesting as are the Trans-Purple Clip Claws.
Build. I managed to pull three out of this set. The two on the outside are 2Rh/1B/1G/1Y/2W. The one in the middle doesn't have any stats yet.
Can you build something -- a frame, station, or starship -- right away? Yes. (+5)
Is it below, at, or above the golden ratio? Above. (-10) (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)
Does it have more than a handful of immediately useful parts? Yes. (+5)
Score: +5 (B+). A decent start for this line of sets.
