Papyrus, sadly, lacks the Illusionist's ability to float, and while his custom job grants him some wacky and comedic defiance of physics, it's not really enough for more practical affairs. Fortunately, he does have something of more use, so, switching to Chemist, he removes his hover board from his pocket space and proceeds to descend after the others, with an exasperated Moogle fluttering beside him.

As he moves, he calls to the others, "IF ANYONE NEEDS A LIFT, I CAN PROBABLY CARRY ONE OTHER PERSON!"

It might be safer than some of the other alternatives, anyway... provided they have good balance and don't mind potentially clinging to a talking skeleton.

He'll wait to see if anyone wants the lift first, but if nobody obliges, he'll start his descent toward that particular grotto.
