The Case of the Missing Cubicuboctahedron

It all started with a simple idea: to make an interesting geometric shape. 2 of my friends and I spent an afternoon constructing an appropriately complex one out of construction paper: the cubicuboctahedron. (Here's a picture of one: http://en.wikipedia.org/wiki/Image:Great_cubicuboctahedron.png )

We brought it to school the next day, and when it was my turn to carry it around, I put it under my desk in English. Then I forgot about it. Two periods later, I rushed up to my English classroom and burst through the door, and the sight before me was heart-stopping. It was gone!

I had no choice but to leave school empty-handed, after confessing to my friends that I had lost it. As we started walking home, one of my friends mentioned to another, "You didn't get to see our cubicuboctahedron!" I added, "And now you can't, because I lost it!"

He responded, "What did its faces look like?"
"Well, it was a sort of cube with star shaped faces," we described.
"Was it green?" he asked.
"Yes!" we answered.
"I found it under a desk in my English classroom," he said. "I gave it to the teacher for safe-keeping."

The next day, I had the slightly awkward task of asking my English teacher about it.
"Did you find-- I left a 3-D shape in here yesterday," I asked.
(Momentary pause)
"Yes!" she exclaimed in her enthusiastic English-teacher manner. "We were admiring it in G-block! Its very pretty," she responded as she reached into a cabinet and returned it to me.
"Thank you," I said, and sat down at my desk, victorious.
Case closed.
