All but one of the competitive stages in Nickelodeon All-Star Brawl are inspired by stages from the Super Smash Bros. series:

• Jellyfish Fields from SpongeBob SquarePants is based on Smashville, introduced in Super Smash Bros. Brawl.

• Harmonic Convergence from The Legend of Korra, and the post-update version of Royal Woods Cemetery from The Loud House, are based on Final Destination, introduced to the multiplayer stage lineup in Super Smash Bros. Melee.

• Sweet Dreams, from Garfield, is based on the frozen version of Super Smash Bros. Melee's Pokémon Stadium, introduced officially in Super Smash Bros. Ultimate, but popularized by fan projects such as the Super Smash Bros. Brawl mod Project M prior.

• Irken Armada Invasion, from Invader Zim, is based on Battlefield, introduced to the multiplayer stage lineup in Super Smash Bros. Melee.

• Rooftop Rumble and Sewers Slam, both from Teenage Mutant Ninja Turtles, are based on the hazards-off version of Smashville introduced in Super Smash Bros. Ultimate, with Sewers Slam - originally intended as a casual stage but adopted into the competitive stage lineup - containing a goop hazard somewhat resembling the wind from Super Smash Bros.'s Dream Land.

• Duck, Duck, Pie!, based on The Adventures of Jimmy Neutron: Boy Genius is based on the hazards-off version of Super Smash Bros. for Wii U's Kalos Pokémon League, introduced in Super Smash Bros. Ultimate.

• The exception to this pattern is Tremorton Joyride from My Life as a Teenage Robot, which is based loosely on Delfino's Secret from the Super Smash Bros. Brawl mod Project M.
