Teeny is a Troll child who's lived beneath Castle Enchancia her whole life due to a misunderstanding between her people and King Gideon, the grandfather of King Roland II.
Because of this, she has never seen real stars, which every troll loves to do, until Sofia clears up the misunderstanding. When Teeny goes to the surface, seeing real stars for the first time, she makes happy little somersaults in the castle observatory. She used to have a habit of sucking her thumb.
She appears again in "The Fliegel Has Landed" and has grown, and so does her teeth. She plays hide-and-seek with Sofia and Gnarly and when a fliegel appears somewhere in the grotto, She stood up, and so does her other fellow trolls. She thinks salamanders are cute.
