Ally:
I was working in the lab late one night
When my eyes beheld an eerie sight
For my monster from his slab began to rise
And suddenly to my surprise
Fifth Harmony:
He did the mash
Camila:
He did the monster mash
Fifth Harmony:
The monster mash
Camila:
It was a graveyard smash
Fifth Harmony:
He did the mash
Camila:
It caught on in a flash
Fifth Harmony:
The monster mash
Camila:
He did the monster mash
Lauren
From my laboratory in the castle east
To the master bedroom where the vampires feast
The ghouls all came from their humble abodes
To get a jolt from my electrodes
Fifth Harmony:
He did the mash
Camila:
He did the monster mash
Fifth Harmony:
The monster mash
Camila:
It was a graveyard smash
Fifth Harmony:
He did the mash
Camila:
It caught on in a flash
Fifth Harmony:
The monster mash
Camila:
He did the monster mash
Normani
The zombies were having fun
The party had just begun
The guests included Wolf Man
Dracula and his son
Dinah
The scene was rockin', all were digging the sounds
Igor on chains, backed by his baying hounds
The coffin-bangers were about to arrive
With their vocal group, "The Crypt-Kicker Five"
