Jesper is a blank flank for most of his life and only gets it by the end of the films timeline, and mogens loves making fun of him for being nearly 30 years old and still not having his cutiemark-- which is just him projecting his insecurities about his own mark, which is an adorable lil manatee~
He tries to keep it hidden but Jesper eventually sees it lol-- oh how the turn tables--
