Hundreds of colorful butterflies flap their wings before your eyes. You yearn not only to see them, but also to help them take off and fly far, far away. But doing this is not as easy as it seems. To help butterflies fly, you need to collect groups of three or more identical representatives of this insect species. To do this, use a special cannon and multi-colored cores. Be prepared for a long and painstaking work and, then, the result will certainly please you. Good luck!
