Morgan rarely shows emotion, only slightly smiling whenever she's dancing or watching others dance. She's sassy, cold, and seems bored most of the time, even admitting it--right after the Ninja showed up--in "Monster Drill". Not even being referee for the Wave Slayers competition excites her. In "Escape from Detention Island", she gets detention for "shaking her booty in a no booty shaking area", but she doesn't seem to be guilty and instead is annoyed.
Never taking things lightly, she is annoyed that her dancing team starts crying when Howard sends them off the stage in "So U Think U Can Stank", and finds it ridiculous that a skeleton is teaching Home Economics class in "Nukid on the Block". Also open for revenge, especially after being sent out before they actually performed, she makes fun of Howard when he and Randy have to act for the talent show.
