[As it turns out, Papyrus is one of the newest Reclaimers, having not actually ever stepped foot on the moon base before. So after the generally emotional (reunion?) chat with his brother, there's nothing for it but exploring. Plenty of people are happy enough to tell him about the biggest sights to see - being used enough to Sans not to be startled by another skeleton - and the Voidfish chamber is one of those sites. He doesn't think to go quietly down the hall, but the sudden silence that falls as he enters is noticeable.]
Uhh... Don't mind me. I'm just exploring. But I can come back another time, if you're talking about me!
[It's somewhere between passive aggressive accusation for the silence, and genuine hope that's precisely what's going on. Papyrus would love for more people to be talking about him. He'd just also like to hear it.]
Voidfish - hey, what was that about disgusting squid things?
