One step inside this spooky castle and you'll know that something weird is going on! You'll have to be careful here because some of the nasties that float around here can't be beat just by inhaling them. The not so famous twins Lololo and Lalala rule this castle of gloom.”

Kirby is standing near the castle's moat when he suddenly sneezes, causing some nearby stars to fall out of the sky and land in the water. He sneezes again, but this time a star clonks him on the head and he loses his balance, falling into the moat.
Castle Lololo is a haunted stronghold filled with spooky enemies such as Two Face, Booler, Flapper, Mumbies, Broom Hatter and Hurly. It is surrounded on all sides by the tropical waters of Float Islands. It features a lot of big rooms with different paths and has a maze-like room with multiple doors leading to other locations in the same room. Halfway through the level, Kirby grabs a Warp Star and crashes through the wall to another area of the castle where Lololo is faced by himself. After that battle Kirby continues through a few more rooms before Lololo & Lalala are fought together.
In Spring Breeze the level is removed, but Lololo and Lalala are still fought as they replace Kabula as the boss of Float Islands. It is likely that Castle Lololo appears briefly though, as Kirby flies to a small island with a castle after defeating Mr. Frosty in Float Islands. The facts that the player battles Lololo and Lalala in this area and the fact that the castle is surrounded by water makes it more likely to be true. The level's intro is also remembered by replacing the original intro of the following level, Bubbly Clouds.
Castle Lololo is the second stage in Kirby Fighters and the third stage in Kirby Fighters Deluxe. The arena takes place in the room where Kirby fights Lololo & Lalala.
Castle Lololo's design closely resembles how it appears in Kirby Super Star and Kirby Super Star Ultra, with alternating orange and yellow blocks and three levels. However, instead of being 11 blocks in width, the room is now 17 blocks wide, each floor is two blocks tall instead of one (except for the third floor, which is three blocks tall).
The main hazards of the stage are Lololo and Lalala, who periodically pass through the doorways. They can push their emerald blocks, Gordos, or Blue Boxes that contain items. Lololo and Lalala can be damaged and defeated (most easily seen using Mke), leaving the individual out of commission for a turn. After not appearing for a turn, Lololo and/or Lalala will return the next turn.
A couple of vaguely familiar characters rule the chambers of this castle. As you might expect, castles have many doors. Castle Lololo is no exception. By pressing Up on the Control Pad while he is standing in front of an archway, Kirby will enter the door and find himself in a new room or area. Make sure that Kirby jumps off the ledge and grabs the Warp Star, which appears just past the long hallway containing Boolers and Mumbies. The Warp Star will take Kirby to the halfway point of the castle. Here, meet and challenge the pushy Lololo.”
