Editing Grumblump Inferno

'''Grumblump Inferno''', otherwise named '''{{world|bowser|7}}''', is the seventh standard course and eighth overall level in [[World Bowser]] from ''[[Super Mario 3D World]]'' and its [[Nintendo Switch]] port ''[[Super Mario 3D World + Bowser's Fury]]'', becoming accessible after the completion of [[A Beam in the Dark]]. It is the only appearance of [[Grumblump]]s, living blocks that roll along preset paths on the lava. Completion of this level unlocks both [[Motley Bossblob's Encore]] and [[Hisstocrat Returns]].

The level is set above a sea of lava, with isolated castle-esque structures found throughout. It starts on a platform with a wide Grumblump nearby. As the player steps on the Grumblump, two [[Skipsqueak]]s drop down onto it and walk along the sides as it rolls, demonstrating to the player how to maneuver while riding it. The Grumblump follows a short straight path to a smaller island and another Grumblump, this one cube-shaped. It follows a more intricate path, including two drops and two [[Fire Piranha Plant]]s on pillars by the sides of the course. What follows is a sizeable section on solid ground, starting with a platform with some [[? Block]]s, an arched bridge leading to two [[Hammer Bro]]s, and a sequence of [[Jump Panel]]s that elevate the player to the [[Checkpoint Flag]].

 

The third Grumblump slides down a lava slope, ending up between two Hammer Bros before a second slope, taking the player to an island which houses some [[Splorch]]es. The fourth and final Grumblump is wide and transports couples of Skipsqueaks, similarly to the first one. After a long path with several turns and a final sliding section, it eventually transports the player to the [[Goal Pole]].
