1. Harem with all the attractive humanoid princesses including bandit princess( finn can be classified as a prince since they seem to be rare), marceline ( because technically she is a queen), huntress wizard, ice queen, samantha ( female dog Jake met in the in "the pit" episode), cake the cat, canyon, water elementals ( the two that can't seem to correctly tell a joke), and some one time characters ( as you can see I want finn to have a large harem in this)

2. Finn has to be different he still has to be adventurous but he also has to be well educated
