Munchkin Koethulhu, the Dutch language version of Munchkin Cthulhu, consists of the translations of Munchkin Cthulhu, Munchkin Cthulhu 2: The Call of Cowthulhu, and Munchkin Cthulhu 3: The Unspeakable Vault, along with 4 exclusive Dutch cards.
Which cards are these?
According to this post on the Steve Jackson games forums, the four Dutch exclusive cards are Verwilderd, Inburgeringscursus, Ontlastingsdienst, and De Dodenrit.
Note that the linked post listed one of the cards simply as Dodenrit while this image on BoardGameGeek shows it as De Dodenrit - so I can't guarantee the listed names are 100% complete, or if there a slight difference in versions between the two sources.
