I have no actual spinners or Ninjago ninjas, so I've built spinners for my mystery ninja. (Found him in a big bag of tinkertoys.) Instructions: Put stud on the bottom of a 2x2 disc; put 4x4 square board on top of all that. Add 2x6 board and 2 2x2 square boards, arrange in a plus shape on the 4x4. Put L pieces on the corners of the 4x4. Put pieces on in the color of your choice, leaving space as shown in pic 2.
