Obi-Doll was inducted into the Jedi order at a very young age, so young, in fact, that Obi-Doll has no memory of it, except for vague feelings of claustrophobia and the smell of cardboard. From the time of his induction until he was twelve he trained inside of the Jedi crèche. Right before his 13th birthday he was kicked out of the Jedi order because Qui-XMas Ornament was being an asshole and didn’t want Obi-Doll as an apprentice. But a few weeks later, after a bunch of shit happened, He took Obi-Doll as an apprentice. So it was ok that Qui-Xmas Ornament was being such an ass.
