Santa needs a little help!

So every year before Christmas I have Derek write a letter to Santa, he also writes one for Trevor each year. This year Trevor dictated and Derek wrote it down word for word. Derek's letter was pretty clear but Trevor's well..... we're still not real sure.

I've taken him to a few stores now and walked him down the toy aisles trying to get some select information from him, and hoping against all hope that he will spot something and jump up and down saying, "A BOX THAT DRIVES!! A BOX THAT DRIVES!!! but no such luck, and so we are left to wonder what exactly that would look like? Anyone else who has had that same problem who can tell me where Santa might pick up a box that drives, would be greatly appreciated!
