One day, Dylan was headed to school but felt like someone was watching him. He ignored the feeling though and got to school. Around lunch time when he was sitting alone at a table, a boy sits across from him suddenly and tries to start a conversation by asking him a few questions about himself. Annoyed by the boy, Dylan gets up and leaves. The next day, the same thing happens, and this goes on for about a week until Dylan starts to talk a bit with the boy. He eventually befriends him and becomes a bit happier. Though one night, when Dylan is studying for a test in his room, he hears knocking on his window. He goes and looks who it was, and it was his friend. Dylan let's him in and talks a bit with the other male, before he's told that his friend was actually...a mutant turtle named Mikey..? It surprised Dylan at first, but he easily got past it and later met Mikey's brothers in the lair. Oh, and he falls in love with Mikey, boom. :)
Here's what he looks like!
