Pin The UFO

There are quite a few people who believe that aliens regularly visit Earth and live among us. They even have some evidence of this. We are not going to open a discussion on this issue, let's assume in the game Pin the UFO that it is. Many colorful aliens got stuck on our planet and a flying saucer flew after them to take them back to their planet. But in order to load the multi-colored creatures into the starship, you need to move the hairpins. You must put all the aliens in the ship. If you come across white ones, they need to be combined with multi-colored ones. Remove the pins in the correct order in Pin the UFO.
