Bowser's Fury is a 2021 platform game bundled in with the Nintendo Switch release of Super Mario 3D World. The player controls Mario through a 3D, cat-themed open world to complete challenges and collect "Cat Shines" to dispel a black sludge from Lake Lapcat and free Bowser from its control. At irregular intervals, Bowser turns the world into apocalyptic night to rain fire on Mario and alter the environment. Its gameplay is based on 3D World, while also adopting elements introduced in Super Mario Odyssey. The bundled release was reported to be the best selling video game of February 2021 in the United States.
