(be any character or OC-)
The hazbin crew(mainly Charlie) thought it'd be a good idea to take a break, especially after the battle with Adam and the exterminators, everyone was worn out, so, relaxing didn't sound bad- charlie pitched the idea of chilling in a near by forest, besides, a little hang out in a calm forest scenery wouldn't hurt--. Everyone decided they could picnic out there, so some brought snacks, drinks, etc. And some even decide to explore, while others just stayed in the main meet up spot-
Lucifer: admirering and cooing at ducks swimming in a pond
Charlie: looking at the night sky with Vaggie
Husk: drinking some booze he brought grumpily, since he was forced to go
Angel: eating and chatting away with Cherri
Niffty: killing insects she saw in the forest
Alastor: just walking around with a book, maybe he was documenting stuff he saw-idk
