Hello, robots come as shown, 2 robots, both work, I do not know what the extra pieces are for, selling as shown. Please view my store and other listings for lots more boys and girls clothes, new and pre owned. Thanks for looking, I ship Mon thru Friday so you get your items fast. I have a smoke free home. I ship to your confirmed ship to address unless you contact me prior to shipment, thanks for looking!!! Most of my items are here today and gone tomorrow! Thanks for adding them your watching list but remember: Even though I am always looking for more, what you see is what I have! When they're gone they are gone! I ship daily!
