Papyrus agrees and doesn't stop Tyki, figuring calling for one person to come here is a safer option than going looking for them and running into any number.

He checks their surroundings for good hiding places, moves into one where he's hidden from the rest of the room, then asks Tyki whether the visor indicates where he is. If they can't hide behind solid objects, sneaking around anywhere or ambushing people will be a lot trickier.
