Anthony Johnson, also known by his avatar Franklin "Mouse" Finbar, is the deuteragonist of the 2017 film Jumanji: Welcome to the Jungle and the 2019 film Jumanji: The Next Level.
Anthony Johnson is a football jock who was once friends with Spencer Gilpin. He convinced Spencer to write his essays and homework for him, allowing him to maintain his position on the football team, but was discovered and sent to detention along with Spencer.
Fridge is portrayed by Ser'Darius Blain as a human and by Kevin Hart (who also played Snowball in The Secret Life of Pets and it's sequel The Secret Life of Pets 2, Darnell Lewis in Get Hard and George Beard in Captain Underpants: The First Epic Movie) as his avatar.
Anthony is initially viewed at first as a selfish, arrogant, lazy, and irresponsible person who is only concerned about football and not homework. He blamed Spencer for getting him kicked off the football team when he made Spencer do his homework in the first place.
Later on in the film, he starts to lose his selfish behavior and starts to become more of a good friend to Spencer.
