This is... certainly a foreboding foe. Fortunately, their numbers should alleviate the matter. Nonetheless, Papyrus is taking a bit of a risk here, donning his Cool Scientist asterisk, allowing him to tap into his blue bones. But perhaps he should give the heads up first.

Rolling his shoulders, he shifts into a defensive stance, glancing back at the others. "EVERYONE, LISTEN UP! I'M ABOUT TO CAST MY BLUE ATTACK!!! THIS SHOULD BUY YOU ENOUGH TIME TO DEAL SOME SEVERE DAMAGE. MAYBE. IT'S WORTH A TRY!!!"

And so with his warning made, he prepared to launch his blue bones. The moment the fight begin, he'd send them flying, hopefully giving the others an opportunity to pummel it to bits.
