Strange Little Verses are scrolls you can find in KCD2 that take you on a treasure hunt through Kuttenberg. You'll find your first one by completing the Master Schindel's Toys activity, which you'll pick up during the Into the Underworld main quest. This walkthrough will show you all the verses you can find and help you find where they lead.
You'll find the first scroll along with a book and an Astrolabe at Goatskin's stash in the underground. The closest entrance to the underground is north of the market in an enclosed yard. It's at the blue circle in the above map.
Once inside, you'll have to turn south and left to reach the stash. The book and Astrolabe need to be returned to Master Schindler, who you'll find at the Scribe's office close to the market to the north.
The verse itself mentions the fountain on Vintners' Street. It specifically mentions the pipes running out of the fountain.
You'll find the fountain on the west side of Kuttenberg, near the fast travel icon.
Examine the fountain's eastern side to find a pipe with a circle drawn under it. Loot it to find Strange Little Verses II.
This verse mentions a "Sir Knight Pail von Bucket," a reference to an archery target called "The Protector of Kuttenberg" along the north wall of the city.
You'll find it between the stone wall and the outer wall of Kuttenberg, marked with a POI marker.
When you get there, loot the noble knight's helm to acquire Strange Little Verses III.
The third verse mentions Eden and it just so happens that there's a Garden of Eden here in the city. Your objective isn't far from it.
Head to the buildings northwest of the Garden of Eden, near the Kuttenberg Market.
There, you'll find an image above one of the columns of Adam and Eve. Go around behind the column and loot the small cubby to find Strange Little Verse IV.
The fourth verse mentions a high place where birds like to make their nests. It's referencing a bird's nest at the top of a tavern in the city.
The tavern is on the northwest side of town. It's called The Emperor Charles Tavern.
Go inside and climb all the way up to the top floor. Walk to the south wall and look up at the small window overhead. Throw a rock at the nest there to knock it down and loot Strange Little Verses V.
The fifth verse speaks about a dragon and St. George. A painting of George himself can be found on a tall yellow building east of The Emperor Charles Tavern.
There, in a small window by an archway, you'll find the final reward for chasing down all the Strange Little Verses:
