The mutated appearance of the landscape really makes me feel like these guys would fit right in with Adventure Time. Seb could be Finn's moral compass since Jake's well-intentioned but a little skewed, Vin could be his loveable bad influence that helps him pack some muscle onto those noodle-arms, and considering all of his crushes in the show were either older than him, scarier than him or both, I can see him falling for Emi.
