The children get excited but it is cut short when the mother answers the door, to find a hulking, disturbing figure in a clown costume armed with a machete. The man laughs and shouts "happy birthday" and hacks Sally's mum with the machete.
Shortly after, the killer clown Bo-Bo ties Sally up to a chair and serves her up a cake with her mother's head on it. He then mockingly says "happy birthday Sally" before letting out a sickening laugh.
