Pipi + Caca Mod

Your Viking has needs. Valheim gains three bodily functions: poop, pee and farts. It's silly, it's synthesised, and it's surprisingly physical.

What it adds

• Poop. Eating fills a hidden urge, digested little by little (bigger meals, more urge).

  • From half-way, a status effect shows, like the cold: Need to poop [K]. Press K to squat and go.
  • At 100 % it happens on its own, wherever you are (as long as you're on solid ground).
  • The poop lands right behind you, and you can pick it up (E)... and throw it. It bursts into a brown splash on impact.

  

• Pee. A second urge that fills on its own, slowly (full in about an hour by default).

  • From half-way: Need to pee [L]. Press L to go, and L again to stop early. At 100 % it starts by itself.
  • You keep walking while you pee (no running, jumping or fighting). A male Viking stands and holds it properly with the right hand, and you aim with the mouse.
  • A female Viking squats instead: she can shuffle along crouched, and the stream goes down toward the ground. The mouse nudges it sideways. Set Pose to force one or the other.
  • The stream is simulated: drops fly with gravity and your own speed, and bend when you turn. They splash on the ground, buildings, creatures or water, and leave wet patches that dry in a minute.
  • Strength follows the urge: a strong arc at first, dribbles at the end. 100 % empties in 10 seconds (50 % in 5).

  

• Farts. A hidden gauge, no status effect and no animation. It fills over time and with each meal. When it's full, your Viking lets one go: just the sound and a faint cloud of gas.

• Sounds. Every sound is synthesised from scratch (no recordings): 4 farts, 3 plops, 2 splats, and pee on the ground and in water.

• Multiplayer. Everyone sees the stream and the pose, and hears the farts.

• Languages. English and French.

Requirements

• Valheim (tested on the current Steam build, October 2026)
• BepInExPack Valheim 5.4.2351
• Jötunn 2.30.2 or later

Install

• With r2modman or Thunderstore Mod Manager: click Install. Dependencies come along.
• By hand: copy the contents of plugins/ (Caca.dll, sfx/, icons/) into Valheim/BepInEx/plugins/Caca/. Keep sfx/ and icons/ next to the DLL.
• Multiplayer: every player (and the server) needs the mod. Jötunn checks this on connect.

Uninstall: delete the folder. The urges are stored in the character's custom data and are simply ignored without the mod. Poop items left in the world or in your inventory disappear.

Configuration

BepInEx/config/lekinox.pipicacamod.cfg. Every setting is reloaded live, a second after you save the file.

Console commands (F5, with devcommands):

• caca [force] and caca_need <0-100>
• pipi [force] and pipi_need <0-100>
• pet (fart now) and pet_need <0-100>
• caca_throw [speed]
• caca_hold x y z [rx ry rz]

Troubleshooting

• The log: BepInEx/LogOutput.log. The mod's lines start with [Info : Pipi + Caca Mod].
• No sound or default icons: check that sfx/ and icons/ sit next to Caca.dll.

Compatibility

• Pure code, plus one item cloned from the vanilla ooze bomb. It shouldn't conflict with other mods.
• Mods that also drive the right arm with IK may fight over it while you pee.

Credits

• BepInEx, Harmony, and Jötunn.
• Sounds are synthesised in Python/numpy (tools/synth_caca.py). Icons were rendered with Blender and Pillow. No generative AI art or audio.
• Built with universal-modder, a game-modding toolkit for AI coding agents. It provided recon, in-game testing and capture, the sound-analysis loop and the pre-release checks.
• AI disclosure: this mod was designed with and coded by an AI agent, Claude Code (Claude Opus 5.5). The sounds were tuned against a second agent that scored spectrograms. All of it was directed and playtested by Lekinox.

License

MIT for the code. The synthesised sounds and icons are part of the mod and under the same license.

Changelog

0.5.1

0.5.0

• Female characters squat to pee:
  • She can still shuffle along crouched.
  • The stream goes down toward the ground and is weaker; the mouse nudges it sideways.
  • There is no hand pose.
  • Pose (Auto / Standing / Squatting) forces one or the other. Other players see the right pose.

• Slower urges: pee now fills in about 1 h 07 (was 25 min), and farts come every 33 minutes (was 40).
• Fixes:
  • A white flash sometimes appeared where the stream hit the ground (a new wet patch showed white for one frame).
  • The stream's brightness now stays under the bloom threshold.

0.3.0

• Farts: a hidden gauge that fills over time and with each meal. When full, a fart (sound only, with a faint gas cloud) and no animation.
