The Monster (Peter Boyle)’s Timeline and Summary

Whoever the monster was before he was a monster is hanged, and Frederick and Igor dig him up.
They accidentally smack an abnormal brain in him, so he's a little crazy when he gets up.
He's sedated and restrained on the operating table, but Frau Blucher releases him.
The monster escapes, plays with a little girl on a seesaw and visits a blind man who accidentally lights him on fire.
He's recaptured by the doctor and taken back to the castle, where the doctor teaches him to sing and dance.
They perform "Puttin' on the Ritz," but an exploding lightbulb scares the monster and sends him into a rage. He's captured again.
Chained by the police, the monster is taunted, but he breaks free.
He kidnaps Elizabeth and takes her to a barn, and yada yada yada, she enjoys it.
Lured back to the castle again by violin music again, the monster's strapped to a brain transfer machine with Frederick and gets the doctor's gift of speech.
When the Angry Mob arrives, the monster speaks loudly and clearly, and the mob goes home. The experiment is finally a success.
The monster lives in domestic bliss with Elizabeth.
