Explosive Clay Dolls

Deidara creates Exploding Clay that is connected to his hands with a thin cord of clay. The clay then rises from the ground, molding itself into human-like forms. Deidara runs chakra through the cords of clay, manipulating the clay substances to attack the opponent. The density of the clay is strong enough to repel and suck in a sword. When cut apart, the clay substances form more human/animal like forms. Deidara then can connect more cords of clay to the fallen clay pieces. Furthermore, Deidara can then use the clay as explosives, attacking the opponent and covering them with clay, which then explodes.

Considering the cords that control these creatures like puppets, it might be possible that this jutsu was inspired by Deidara's old teammate, Sasori of the Red Sand.
