“Sippy Cup” is an alternative song where the Cry Baby character finally reveals the events that follow what takes place in “Dollhouse.” In an interview, Melanie told SPIN Magazine:

The song is basically the bridge between the Dollhouse EP and the Cry Baby album. […] This song is about what actually “goes down in the kitchen,” a deeper look into Cry Baby’s family life. This is my favorite video I’ve done so far.

In the video, Cry Baby’s mother from the “Dollhouse” video is shown distraught and drunken on the floor. Suddenly her drunken husband stumbles into the house, clutching an unfamiliar woman who is also drunk. They begin to dance in the kitchen as the wife pushes herself to her feet. The wife, seeing her husband has cheated (which was also suggested in the lyrics and video for “Dollhouse”), then murders him and the woman. When Cry Baby comes downstairs and discovers the bodies, the mother catches her with chloroform, chains her to her bed and poisons her…with a sippy cup.

The story and illustration for this song appears on the 7th page of the Cry Baby storybook, reading:

She watches momma sip a drink
Out of a sippy cup that’s pink
Because of that you’d never think
That she’d pass out under the sink
