Big Twin Birds - one of the variants of the basic C1 technique based on explosive clay. The user molds from clay two large birds that can fly and be used as a means of transport or for attack. These are large white clay creatures, similar to strange birds. They are completely smooth and matte, white in color, as if molded from a single piece of white clay. They have a very long, flexible neck and an elongated head with a long sharp beak. Instead of eyes - just small black dots. On the back of the head and along the neck protrude backward long sharp spikes. Their wings are huge and consist of separate long plates, similar to blades or to cut paper. Their tail also divides into 6 similar plates.
