Mouthwashing Tulpar: Ship Layout and Secrets Explained

What Is the Tulpar in Mouthwashing?

The Mouthwashing Tulpar is a stranded space freighter where five crew members face dwindling supplies and nowhere to escape. Learning its rooms helps you find essential items and follow a story that jumps between life before the crash and the desperate months afterward. The wreck’s power will run out within six months, and its food supplies will run out much sooner.

The Pony Express crew consists of Captain Curly, co-pilot Jimmy, medic Anya, mechanic Swansea, and intern Daisuke. You explore the ship through Curly’s perspective before the crash and Jimmy’s afterward, when emergency insulation foam blocks damaged sections.

Story spoilers below, including the cargo hold reveal and the ship’s final destination.

Key Rooms and How to Navigate Them

The Tulpar’s familiar spaces serve different purposes as the crew’s situation deteriorates. Use the common room and main corridor as landmarks when moving between objectives.

Common Room and Kitchen

The common room contains the dining table, recreation area, and kitchen equipment used during the birthday cake sequence. Its warm colors and dated furnishings make it feel different from the cold corridors outside.

To reach the medical bay from here, leave through the door opposite the recreation area and follow the short hallway.

The kitchen’s ingredient dispenser and mixer become important during specific story tasks. When preparing the birthday cake, consult the recipe book and use the scanner to reveal the sweetener code.

Medical Bay

Anya treats Curly here after the crash. Several objectives bring you back to his bedside, including administering painkillers.

During the early post-crash sequence, speak to Anya about the captain’s scanner before searching the cockpit. Later, she directs you toward additional medicine behind foam in the corridor leading to the medical bay.

The room’s worn institutional appearance fits its uncomfortable role: this is where the crew must provide ongoing care with increasingly limited resources.

Cockpit

The cockpit is central to both the crash and your search for access equipment afterward. Much of it is covered in emergency foam following the collision.

When looking for the code scanner, check the floor on the left for its purple blinking light. The supply locker on the right remains accessible despite the damage.

Cargo Hold

The cargo hold connects the crew’s immediate survival problem to the game’s title. When they finally open it, they discover boxes of Dragonbreath mouthwash instead of the food or useful supplies they desperately need.

Its contents become part of the crew’s decline, particularly Swansea’s return to drinking.

Scanner Locations and Important Access Codes

The code scanner reveals combinations hidden in darkened areas. Select it from your inventory, activate it, and aim at the relevant surface.

These combinations apply to different locks, so match each code to its destination:

Lock	Code	Where to Find the Clue
Cargo hold door	4517	Scan the darkened area on the cargo hold door
Fire axe case	2609	Scan the case near the utility room door
Gun case	739	Scan the dark area at the bottom of the cockpit locker

The fire axe appears in the pre-crash sequence where Daisuke becomes trapped in foam. Open its case and use the axe to free him.

Later, the axe also lets you break through foam blocking access to a medicine locker. Collect both the painkillers and isopropyl inside; each has a role in subsequent objectives.

The Utility Room, Vents, and Cryogenic Pod

The utility room becomes a point of conflict because Swansea guards its entrance and says the interior is blocked by foam. When Jimmy gains access, the room is more intact than Swansea claimed.

Inside are the cryogenic pods, with only one still functioning. Swansea intends to preserve that remaining chance of survival for Daisuke.

The room also contains a ventilation route into the medical bay. Jimmy persuades Daisuke to enter it, leading to the injuries that precede his death. This passage connects two essential rooms while exposing how dangerous the damaged ship has become.

At the end of the game, Jimmy carries Curly from the common room to the utility room and places him inside the remaining operational cryogenic pod.

Why the Ship Feels So Claustrophobic

The Tulpar’s corridors resemble those of an old submarine: cold, narrow, and unwelcoming. The common room counters them with kitschy 70s decor, while Anya’s office resembles a dingy school nurse’s room. These mismatched interiors make the company’s attempts at crew comfort feel hollow.

The orange sunset in the common room comes from a screen stuck in sunset mode. It provides an image of an outside world without giving the crew an actual view beyond the ship.

You never receive an exterior view of the Tulpar, and there are no real windows offering a reassuring look into space. The interior defines the crew’s entire visible world.

Pay attention when recognizable routes stretch, loop, or lose their doors. Mouthwashing uses distorted versions of familiar spaces during Jimmy’s hallucinations, turning the layout you have learned into something threatening.

Even the broken Polle statue carries a specific story detail: Jimmy broke it, and Swansea, drunk on mouthwash, found it hilarious. The damage around the ship reflects the people trapped inside it as much as the collision itself.
