She threw 2 this time.

Sans evaded with realative ease. It'd be almost cat-like if he had muscles. He decided to retaliate a bit, deciding it was only fair if he put in at least the minimal effort. He hurtled an arrangement of both blue and regular attacks, though the pattern itself was still borderline Froggit levels of orthodox.

Undyne took no damage, beginning to throw spears in the double digit amounts.

Sans moved out of the way of each one, a small part of him actually getting into the match in spite of himself. After a few more turns, he sighed inwardly as an idea crossed his mind. oh, why not? When his move came back around, he pulled a fast one, grabing ahold of Undyne's Soul with Blue Magic and finally putting one of his more complex patterns on display, definately an attempt to catch her off guard even though he intended to deny it later.

SHe was caught of guard, and was hit at first, before standing still and not getting hurt by the Blue attacks.

It seemed like Sans wasn't going to repeat that trick anytime soon, for his next few attacks, while no longer basic, weren't anything particularly special.

Undyne dodged, and kept going with spear throws.

They went back and forth like that for about five more turns before Sans began to visibly tire. He still had yet to be hit, though.

Undyne finnaly tried out her green Soul bind attack thing, and Sans couldnt move as soul marshmallow spears flew at him.

Sans let out a huff, bringing up an extended bone in front of himself to block.
