Level 16 has you assembling kebabs. Use the picture in front to see what the kebab needs to look like. It will only show for a few seconds so you need to memorize it. You build the kebabs bottom to top so it is the reverse of how you might think at first.
Once you have made the kebab, drag it onto the plate. You'll need to make about 5 in total to proceed and they will get more and more complex as you go.
