Here are the instructions and parts bag.
Here's the frame I designed. Not great but I was in a bit of a hurry.
Can you build a frame, or frames, right away? Yes. (+5)
Is it below, at, or above the golden ratio? Below. (+5) (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: 20 (A+). Our second Lego set with an A+ rating. I get the feeling that more Mixels sets will achieve this rating.
