Mice Walkthrough

Start the Quest: Talk to innkeepers in Tachov about the Zhelejov/Tachov feud. Innkeeper Prochek will give you the quest to prank Old Olbram's bull. You can do this quest before or after the 'Frogs' quest.

Get Sleeping Potion Recipe: Speak to Blacksmith Radovan in Tachov about sedating an animal. If you've completed 'The Blacksmith's Son', he'll give you the recipe. Otherwise, you can convince him with a Craftsmanship skill check or pay 75 groschen. The recipe requires boiling poppy and thistle in oil, then adding herb paris.

Get Paint: Travel to Troskowitz and find Tailor Bartoshek. You can buy the paint for 60 groschen, or attempt a Speech check by saying, _"That's quite expensive."_ If successful, he'll give you the paint for free.

Concoct Lullaby Potions: Gather the ingredients: poppy and thistle (found in fields west of Troskowitz) and herb paris (can be bought from the alchemist in Troskowitz or found in an herb garden south of Trosky Castle). Use the alchemy bench in Troskowitz to brew the potion: add oil, 1x poppy, boil once, add 1x thistle, boil once, add ground herb paris, and pour. You need three doses.

Paint the Bull: Head to Zhelejov and locate Old Olbram's estate. The bull is usually in a stable or pen. Sneak into the stable and spike the trough with the potion. Wait until at least 22:00 hours when most guards are asleep. You may need to wait longer for the remaining guard to briefly leave. Sneak in and paint the bull. Alternatively, you can use a house to the west with a locked door to access the stables via planks. Consider using Nighthawk Potions to see in the dark if needed.
