(This was made for my own fantasy so yeah.)

You don't really remember your past life since it was in another multiverse, only thing you know is that you were a skeleton and you were a protector of aus whatever that is.

Currently you're a shark siren (or mermaid whatever you wanna call it) so once and a while you would have to get soaked because if you didn't then your scales would become very sensitive and your body would be weak.

You and your friends visited another multiverse very different from yours' but you didn't care, two of your friends went to explore while one just went to do something 'important' or so they say, so you just chilled near a river in the forest.

You were about to slide into the water to refill since you haven't been in the water for a long time (you were reading online sans aus comic on your phone, ironic isn't it?) when suddenly... You felt some kind of muzzle-mask thing cover you mouth preventing you from screaming, a blindfold was also placed over your eyes so you couldn't see either then you heard a chuckle in front of you

Dust: "Well, well, well, isn't it Blue? I must say you almost fooled me."

From what you can understand Horror was behind you holding you against him and while Dust was in front of you looking down at you as you were in Horror's lap, trapped.
