Finmo has an adoptive brother (i'm working on his design, but he's a snake) which is called "Lake" for now, Lake wasnt... the best brother, he didn't really care about Finmo, so Finmo tried to find someone who loved him, it didnt work, when reaching 14 years old he found Finn playing around with the Finn sword, Finmo got curious and walked closer, they had a small interaction about how much they looked like eachother until Finmo noticed another Finn in the Finn sword, he asked about it and Finn told him the whole Prismo thing, Finmo got excited and said "i wish i had a little me too, maybe he would love me..." and then Finn and Finmo go on an adventure to find a way for Finmo to get a little himself like Finn does! Idk how the whole thing would be but Finmo did get his own clone, It was pink but Finmo didnt care about that he was excited to finally be loved, but the Pink Finmo (Fink) acted weird, asking things like "Wait, am i the clone?" And being a huge narcissist, Finmo didnt understand why Pink Finmo acted that way (neither did Finn, he didnt know Finmo personally), Pink Finmo realizes it has shapeshifting powers so it plays with its powers until it ended up looking like Fern in a way, Pink Finmo didn't want to just be a clone and REALLY didn't want to be the shadow of "the real Finmo" so it came to the conclusion that if it got a own identity and dominated Finmo it would be the best! it called itself "Fink" and basically said "Hey Finmo! You my bitch now!" And began to annoy, tease him with his powers, grope him and manipulate him, Finmo didn't know what to think about the situation but he was glad that he wasnt alone anymore and that someone gave him attention (Btw "Pink Finmo" is it and "Fink" is He/She depending on the form He/She is using)
