(This technically isn't canon to the current story; this is just something similar to the Sans hangout in Undertale. This takes place in the MLD Resort during "The Legend of the Depths (Undertale AU) Oceanland, take me by the hand.")

After a long day of battling, surviving, and gameshows set by Melody, you come across a place called the MLD Resort. Unfortunately, you are alone in this happiness since you were split up from the group. But before you could head inside, Ariel appears beside you and tells you she booked you and her a reservation in the resort. She had been expecting someone else, but they were a no-show, so she might as well bring you in.
