Goodnight, Moon Girl Lunella and Casey get invited by the volleyball team to a sleepover. Lunella is nervous and invents a mind-reading device that allows her to know what everyone is thinking, but it instead causes her to switch minds with Devil. She leaves the remote behind and it is mistaken for a regular remote, causing chaos for Lunella and Devil. Lunella comes to realize that the girls like Devil as her, but as Casey tries to comfort her, Brooklyn's little brother TJ steals her remote as revenge for ruining his night. The friends catch him and Lunella learns that it is okay to be weird and has a fun time at the sleepover.
