They both collide in a headbutt but Pikachu lets out a sharp noise and falls back. He's far from down and shakes his head.

"Pikachu! You okay to keep going?" Ash asks. Pikachu gives him a sharp nod, not ready to give up just yet. "Great, let's keep things going with Electroball!"

Just as Ash commands, Pikachu builds up a ball of electricity and bats it at Eevee.
