Sans was telling me about the beach event.

[He doesn't sound to enthused himself; he's not a huge fan of the beach, especially when it's not even the real beach.

And okay, wait up on that next part a moment.]

'Skipping planets?'

[As for the monsters--]

That makes sense. So, presumably, we should be able to catalogue what monsters are present in the caves by what monsters arrived each month.

[And therefore might also have some ideas on how to handle each of them.]
