Hippo is a species and territory antagonist In the 2017 film, Jumanji: Welcome to the Jungle.
the players land in the Jumanji dimension after selecting their avatars. While getting used to their new characters, Bethany Walker discovered in a nearby river reflection that her character avatar was Shelly Oberon, completely unaware that a Hippo was swimming in the river behind him. The Hippo (presumably agitated by his screaming) submerged from the river and ran up behind Shelly, seizing him in its jaws and (seemingly) killing him. Fortunately Shelly had 2 more lives to spare and regenerated back into the game, but the Hippo was still riled up and gave chase to the players.
