Mona 4 heard from her father about how Crescent explores dungeons and crypts as he found most of the Elemental Weapons of Siwa and 2 of 3 Divine Weapons. Mona 4 curious decided to sneak off with Crescent by hiding in his Shin diaper, confused why there's a Shin Plushie in there. Mona 4 wanted to explore something with Crescent, so he decided they'd explore something light such as an ancient ruin.
Mona 4 did her best not to trigger any traps, but Crescent made Shin set them instead. Where Shin ended up as a diaper. Mona 4 also tried to read the writing, but couldn't make it out whereas Crescent told her not to step on cracked tiles or the ceiling would fall and squish them. Shin did trigger it and as they got away from the trap, Crescent flew up and peeled Shin off the ceiling and folded him up into a diaper for Mona 4 to wear. They soon found many treasure, Mona 4 wanted to keep an ankh necklace she found, but when she took itl the ceiling collapsed and the treasure room was blocked by a rockslide, Mona 4 feeling bad immediately apologized and asked to keep adventuring.
Crescent of course let is slide as it was her first and theirs always another way into the ruins that they could find, Mona 4 wanted to give Crescent the Ankh, but he let Mona 4 keep it as she had it first and Crescent does want her to have a victory spoil and he even threw in a Pampsune for free until its full. So they decided to camp outside the ruins and plan another way in tomorrow.
