Friday Night Funkin' Wiki

Week 4, titled Mommy Must Murder, is the fourth set of levels in Friday Night Funkin'. It was released on the 27th of December, 2020.



Boyfriend faces off against Mommy Mearest, the pop-star mother of Girlfriend.


Week 4 takes place on "The Limousine." This location is set around sunset on top of moving vehicles on the highway going left where cars regularly drive by in the opposite direction. Visible on top of the limo in the background are several Henchmen with pinkish-red skin, a flattop haircut with two pointed ends to resemble a set of horns and a deviously large grin wearing open black jackets with no shirt underneath, black pants, black sneakers and sunglasses. They are constantly grooving to the beat. Another one of these Henchmen can be seen driving the limo in front with an arm resting out on the window. The limo in front has a hood ornament in the shape of Daddy Dearest's face.

Unique Effects

As the whole location takes place on moving limos, Boyfriend, Girlfriend and Mommy Mearest all have their hair constantly blown around by the wind. This applies to all tracks.

During the last track, the dancing Henchmen alter their regular choreography to fit the tempo of the song better.

  • Week 4's title is a reference to an unreleased game ninjamuffin99 worked on with PhantomArcade called Must Murder Mommy.
  • Originally, the Henchmen on the background limo were supposed to be killed off by getting hit by a light post, but this was scrapped to save on development time. PhantomArcade stated that this feature would be reimplemented in the future.
  • Before update 0.2.6, Boyfriend, Girlfriend and Mommy Mearest lacked the hair physics effect. However, once this was added, Girlfriend no longer briefly cries when Boyfriend misses a note for the whole week as she lacks the sprites for it with the new effect.
    • Before the same update, Mommy Mearest also lacked a danger icon.
