A HAL Room is a secret area in any given Kirby title, where elements of the stage spell out the letters H A and L. This is a direct reference to HAL Laboratory, the studio that develops the Kirby series.
To reach a HAL Room, a specific path and/or series of doorways must be taken in a specific stage. These paths are usually hidden and require a discerning eye, specific movement, or just plain patience to reveal. The room itself usually features its own music, and often contains rare Copy Ability pedestals, and plenty of Food and other collectibles.
Though these rooms are secret, their locations are usually telegraphed to the player through cryptic screenshots showcased in the credits.
HAL Room Locations
Kirby's Adventure / Kirby: Nightmare in Dream Land
In Kirby's Adventure, a HAL Room can be found in Vegetable Valley - Stage 2. When the Warp Star is reached, Kirby has to walk past it, run up against the right end of the screen for a little while, then fly back for a moment. Once the Warp Star platform is out of view, Kirby then needs to go back toward it. If done correctly, the star will be gone, and Kirby will be able to proceed further right to reach the formation of Star Blocks that spell out 'HAL'. Once Kirby returns to the left, the Warp Star will be there again.
While the HAL room is still present in the level map in Kirby: Nightmare in Dream Land, it is not actually accessible as it is no longer possible to make the Warp Star disappear.
Kirby Super Star Ultra
In the Illusion Islands stage of Revenge of the King, there is a Post that can be pounded along the route to the castle. Doing so uncovers a Food item and a hidden entrance to another area. In this area, Kirby has to battle Mr. Tick Tock. After defeating him, Kirby can progress to the right, over a wall, and find the HAL logo in Star Blocks. Near the exit door, Kirby can get an Invincibility Candy.
Kirby's Return to Dream Land
A HAL Room can be found in Cookie Country - Stage 4, in the first area. After reaching the end of the path, Kirby needs to walk all the way to the end of the screen, wait there a short moment, then head back the other way, to find a pillar of land has moved downward to reveal a new doorway. Through this door is a walk to the HAL Room, which contains the Wing, Hammer, Fighter and Ninja abilities. Breaking the Star Blocks that spell HAL also reveal items.
Another HAL Room can be found in Egg Engines - Stage 5, in the third area. A conveyer at the end of the hall drops a number of Halcandle Dees in front of Kirby and the normal door forward. However, if Kirby bypasses the door and heads up the conveyer, he can enter an obscure hole at the back of it to reach a series of cannon firings, and the HAL Room, again made of star blocks. The Whip, Water, Leaf and Spear abilities can be obtained here, which happen to be abilities introduced in this title.
Kirby's Dream Collection
Kirby: Triple Deluxe
The first HAL Room can be found in Fine Fields - Stage 3. To unlock it, Kirby must first walk all the way to the right end of the area, in the background, wait there a short moment, then return to the spot where Kirby first entered the area to find a new 3-D Warp Star. Taking this star places Kirby in an area he couldn't get to before, where he must then walk to the left to find the HAL Room. This room contains the Wing, Leaf, Fighter and Wheel abilities on pedestals.
The second HAL Room is found in Royal Road - Stage 1. Following the fight against Gigant Edge, Kirby can find a secret area at the very right of the screen that contains some Point Stars and a Maxim Tomato. If Kirby goes directly up from where the Maxim Tomato was and presses up in front of the moon, he enters an invisible door. The room is behind this door. It contains some copy pedestals, a Keychain, and several 1-UPs.
The third and final HAL Room can be found in Royal Road - Stage 5 in a special area where Kirby must contend with 3D Securitron Blocks that will box him in. In the third of the rooms, once the blocks stop extending, Kirby must wait next to the door for 86 seconds, which will cause the blocks to retract followed by three more sets of blocks extending, in the shape of the letters H A and L. If Kirby survives this, another door will appear leading to the room.
Kirby Fighters Deluxe
In the stage VS Kracko on Very Hard difficulty, tiles on the floor read "HAL".
Kirby: Planet Robobot
The first HAL Room can be found in Patched Plains - Stage 3. At the very front of the train, Kirby must activate the Warp Star, but instead of riding it, he must then backtrack and find an area where he collected a Code Cube. There a new 3-D Warp Star will have appeared to take him into the background, where he will then find a door to another room. This room has a chute with some 1-Ups in it, which is reward enough, but yet another secret passage can be found in this room, which will lead to the HAL Room in question.
The second HAL Room can be found in Access Ark - Stage 1. After defeating the second Security Force, a nook can be found on the wall beside the door to the next room. The nook leads to a big room containing two portraits of President Haltmann. The right portrait has a tear in the top right corner, which Kirby can enter to reach the HAL Room. This particular HAL Room has very large Star Blocks and Copy Essences of the three new Copy Abilities introduced in Planet Robobot (Doctor, ESP and Poison) as well as the elusive Smash Bros. ability. This HAL Room plays the title theme of Dedede's Drum Dash Deluxe.
The third and final HAL Room can be discovered in Access Ark - Stage 4. At the very end, some extending walls will box Kirby in with the goal door. Instead of using this door, Kirby has to wait in this room for 86 seconds. After that time passes, another door will appear which will take Kirby to a room where more extending walls will spell out HAL.
Kirby Star Allies
There are three HAL rooms in Kirby Star Allies. They are as follows:
|HAL Room locations in Kirby Star Allies Story Mode|
|Level||Stage||Image||How to reach||Notes||Copy Essence|
|Dream Land||Fruity Forest||First, Kirby and his allies must walk all the way up to where Whispy Woods is, but don't actually initiate the fight (walk up to where his canopy can be seen and the background music fades out). Then, Kirby must backtrack all the way to the beginning of the stage. A door will appear leading to the HAL room.||
|Jambastion||Heavenly Hall||In the very last part of the escape, where large chunks of rock are falling down from the sky, Kirby and his friends will need to wait for 86 seconds. A door will then appear leading to this room. The HAL letters in this room are formed using Electro Saw guide wires.||None|
|Far-Flung Starlight Heroes||Jambandra Base||At the very end of the stage, Kirby and his friends can find a hidden door to this room above the stage exit by 'entering' Popstar as it appears in the background.||
- There are three notable recurring patterns of HAL Rooms based on how to reach them.
- Reach the end of one room and backtrack: This pattern first appeared as Vegetable Valley Stage 2 in Kirby's Adventure. This original HAL Room was placed into the game without the lead designers' knowledge, but similar HAL Rooms in later games were.
- Jump into an obscure doorway: This pattern first appeared in Illusion Islands in Revenge of the King; a main game in Kirby Super Star Ultra. Often, HAL Rooms are hidden through obscure passageways which either represent the dark area of a doorway without the full model, or may be hidden inside suspicious-looking background elements. A good number of these also lead to secret areas that are not HAL Rooms, such as the doorway inside the Moon in the original Kirby's Dream Land and Kirby's Adventure.
- Wait in a room for 86 seconds: This pattern first appeared as Royal Road Stage 5 in Kirby: Triple Deluxe. The number 86 is a reference to the Japanese pronunciation of HAL (ハル), which can also be separated into 8 (ハ) and 6 (ル).
- A Broom Hatter is usually found sweeping on the L-letter blocks.
