Each one shares one of the cube's 12 edges, and one of the octohedron's 12 edges. A man has to get a fox, a chicken, and a sack of corn across a river. He has a rowboat, and it can only carry him and one other thing. If the fox and the chicken are left together, the fox will eat the chicken. If the chicken and the corn is left together, the chicken will eat the corn.
Money is also welcome.
And do NOT ask me if you can have my stuff. It's annoying always having to say no. I'm going to put the email of the next person who asks me for any of my Disco guys up on the main page for everyone to spam. Thank you, and have a nice day.
