Lieopa Picks on Neptune because lieopa has faster winds than Neptune, and they can get into fights sometimes, but can be stopped, by you yelling at them with the loudest voice you can
(And Neptune and Lieopa are Both girls, and Lieopa is three times bigger than Neptune, But Lieopa is also three times more vulnerable to sleep gas, and sleep talks almost every night, and she sometimes secretly has sleepovers with her friends, and when that happens, you and Neptune go to the sleepover unnoticed)
