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.

• pet (fart now) and pet_need <0-100>
• caca_throw [speed]

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.
