Headache Headquarters was previously removed on the 8th of April 2026, though it has been made available through the Sandbox mode later.
It is not accessible anywhere else in the game. This page will attempt to include information about both the version before removal and its re-added version.

"The brain rot has begun!"

―Headache Headquarters being activated

Description

Headache Headquarters was a map set in a laboratory, only playable by sending "dop dop yes yes" in chat on Wave 0 during April Fools, after the mode/map vote but before the first wave starts. It has been made available through Sandbox mode, without the Brain Rot modifier being applied. Triumphing this map for the first time gave the Toilet Scout skin, if the player did not have it already. Otherwise, the rewards were the same as Easy mode, but boosted by 50% (60% if the map originally chosen had All Paths).

Headache Headquarters had the Brain Rot modifier, which replaced all enemies except the Necromancer, Speedy Boss, Enraged and Brute. Additionally, based on the map that was chosen in the beginning, it may have had additional modifiers, like the Talk Like a Pirate Day or All Paths. While they would not make the map harder, they would affect the appearance of enemies or increase the rewards. When opened in Sandbox mode, it has no modifiers.

Design & Path

Headache Headquarters takes place in a laboratory. The room the map is located in has grey walls and floor. It is quite empty, only having a few grey crates and what appears to be multiple monitors close to each other. On the walls, multiple screens can be found. There are also a few windows and gates, through which various halls are visible. These halls have doors, vending machines and benches. Multiple grey metal pipes can also be found on the walls.

The black path starts at the black door and ends at the white one. The path goes straight and then makes two loops, with a single straight path between them. After these two loops, the path goes straight again.

Rewards

The game calculated how many Coins and EXP you received based on how many waves you survived and if you won a match. During periods of 100% more EXP (Friday – Sunday), any EXP earned was multiplied by 2x through the XP Boost modifier. The VIP gamepass also multiplied any EXP earned by 1.25x through the VIP Boost modifier. These two boosts were additive. Regular EXP boosts were multiplicative with other modifiers present on this map.

Any rewards that ended in a decimal point was rounded down, no matter the first figure of the leading decimal.

When activated in Sandbox mode, it gives no rewards. When activated in a real match, rewards were calculated as:

April Fools 2026
Coins Reward	EXP Reward
( 200 ÷ (1 + [(20 ÷ Current Wave) - 1]^1.3) + 50 (Triumph Only)) × 1.5	( 50 EXP ÷ (1 + [(20 ÷ Current Wave) - 1])) × 1.5
April Fools 2025
Coins Reward	EXP Reward
( 250 ÷ (1 + [(25 ÷ Current Wave) - 1]^1.3) + 50 (Triumph Only)) × 1.5	( 50 EXP ÷ (1 + [(25 ÷ Current Wave) - 1])) × 1.5
April Fools 2024
Coins Reward	EXP Reward
( 200 ÷ (1 + [(25 ÷ Current Wave) - 1]^1.3) + 100 (Triumph Only)) × 1.5	( 50 EXP ÷ (1 + [(25 ÷ Current Wave) - 1])) × 1.5

Triumphing it for the first time in a real match also gave the Toilet Scout skin.

Badges

There was also one badge which can be obtained when playing on this map. It is:

Wave Structure

The wave structure was similar to Easy mode's but most enemies were replaced by their stronger variants because of the Brain Rot modifier.

• The Toilet replaced the Normal.
• The Streamer replaced the Speedy.
• The Chad replaced the Slow.
• The Metal Toilet replaced the Normal Boss.
• The Ninja Toilet replaced the Hidden.
• The Png Bot2 replaced the Breaker2.
  • The Png Bot2 also spawns Png Bot upon death.
• The Brick Man replaced the Skeleton.
• The Armored Toilet replaced the Armored.
• The Megatron Toilet replaced the Slow Boss.
• The Pro Streamer replaced the Hidden Boss, though this cannot be seen due to the Hidden Boss being removed entirely from Easy mode.
• The Arrow replaced the Bolt, though this cannot be seen due to Enraged replacing the Bolt.
• The Png Bot4 replaced the Breaker4, though this cannot be seen due to Breaker4 being removed entirely from Easy mode.
  • The Png Bot4 also spawned Png Bot3 upon death.
• The Toilet Boss replaced the Grave Digger, though this cannot be seen due to Brute replacing the Grave Digger.

The Necromancer also had its health increased to 1,200.

The waves in Headache Headquarters followed these timings:

Strategy

• The Ace Pilot can be useful here, as this map has two loops which are ideal for its circling range.
• As the paths are quite close to each other, high range towers like the Turret, Mortar or Ranger can easily cover most or all of the path on this map.
• While this map has quite a lot of cliffs, most of it far away from the path, while the ones close to it are limited, making cliff towers less useful here.
  • The Ranger, because of its high range, can actually reach all the paths on most spots, making it still useful.

Original Strategy

This section contains strategy for Headache Headquarters in its Aprilini Foolsini Eventini state. While it could still be used if the player attempts to recreate it by applying the Brain Rot modifier and starting an Easy mode match, due to changes with the game this may not be perfectly accurate.

• You can earn extra money before the mode starts by placing a Farm and upgrading it before saying "dop dop yes yes". You will be awarded the cash spent on the Farm and the extra amount it generated, allowing the purchase of upgrades or towers that you could not normally afford on the first wave.
• It is recommended to select a map with the All Paths modifier, like Infernal Abyss or Winter Stronghold, as modifiers are carried over from previous map to Headache Headquarters. While this does not make the match harder, since the map only has one path, it will increase the rewards gotten at the end of the match.
• Early-game towers with decent DPS, like the Golden Scout, Electroshocker, Golden Cowboy or Militant can be very effective here.
• High DPS towers like the the Accelerator or Minigunner are recommended though it may be hard to afford them due to how little cash the enemies give, especially in higher player counts.
• The Ace Pilot and Pursuit can be useful here, as this map has two loops which are ideal for their circling range.
• The Medic can be useful at shielding towers from stuns while providing minor buffs.
• The Commander and DJ Booth are highly recommended on this map.
  • The Commander can be useful at boosting your tower's firerate, giving them more DPS and making dealing with the much stronger enemies easier.
  • The DJ Booth can be useful at increasing the range of your towers, in some cases allowing them to cover most of the map, while also decreasing their upgrade costs.

Trivia

• Headache Headquarters was based on the Skibidi Bunker, which originates from episodes 67-70 of Skibidi Toilet.
• When going out of bounds using free cam, an image of the Prowler Goku meme could be found.
