S2E15 King Butterfly screaming 'food!'

King River Johansen-Butterfly and his family in "Game of Flags".

The Johansen family is a Mewman family of barbarian royals that are native to Mewni. They live in a kingdom to the east of Butterfly Castle.


Little is known about the Johansens outside of their association with the Butterfly family and other royal families of Mewni. They are predominantly barbarians who act uncivilized and rowdy and like to eat, compete, and roughhouse. Due to the matrimonial union between Moon Butterfly and River Johansen, the two royal houses are one extended family. Some time after the two families became one, they started holding an annual family reunion, as revealed in "Game of Flags".

In "Game of Flags", the Johansens' barbaric personalities conflict with the well-mannered and uptight members of Moon's family, and they employ brutish and underhanded tactics in the titular contest.

According to young River in "Moon the Undaunted", Johansens apologize to others by giving them an "apology meat"—a leg of meat with the word "SORRY" carved into it.

In "Club Snubbed", the Johansens are among several royal families of Mewni that take part in the Silver Bell Ball.

In "Stump Day", some of the Johansens are present at the celebration.

  • According to Dominic Bisignano, the Johansen family uses a calendar based on felled stags, and River is 17 "felled stags" old.[1]
  • Although the Johansen Clan primarily dresses in animal skin, a young River wore civilized clothing similar to those worn by the Butterfly family.
