Nutty Noon is the final level on Planet Popstar, and thus combines all the game's previous elements in its levels. Nutty Noon also introduces abstract and odd enemies, like Juckles and Gemras. Since the majority of Nutty Noon's levels takes place in the sky, most of the enemies have the ability to hover or fly, such as Owgulfs, Ceruleans, and Pactos. Kirby can use Super Abilities to clear the way in some stages, revealing dimensional rifts.
Stage 5 of Nutty Noon pays homage to the level 7-2 of Kirby's Adventure and its remake, the last level of Iceberg in Kirby's Dream Land 3, and level 5-3 of Kirby: Squeak Squad. This level is a huge mid-boss rush and in order to obtain the Energy Spheres in the next room, Kirby must inhale the previous room's mid-boss. If Kirby goes through a hidden door in this level, he will have to fight different mid-bosses than normal, the Energy Sphere puzzles will be more challenging, and he will have to move right to left, instead of left to right.
After finishing all the levels, the player may challenge Grand Doomer. Before Kirby fights him, he will have to go through a tower that resembles the mid-boss tower in Kirby's Adventure (and its remake).
- A remix of King Dedede's theme plays in the tower of Stage 5 and a remix of Grape Garden's music plays in Stages 3 and 4.
- The music for Stage 2 was remixed as the music for the research facility in Stage 3 of Resolution Road in Kirby: Planet Robobot.
