Note: Ratigan's henchman Bartholomew falls into some alcohol and emerges very drunk and calls his boss "the world's greatest rat". Since Ratigan hates being called a rat and prefers the term of "a big mouse", he sentences him to death at the hands of his pet cat, who eats him up while he's still drunkenly singing of Ratigan's glory, unaware of what is about to happen despite Ratigan telling him.

Note: Professor Ratigan and his henchman Fidget, a peg-legged bat with a broken wing, are attempting to make their escape in a small pedal-powered airship with Olivia Flaversham as hostage. Fidget grows tired of pedalling and suggests lightening the load, gesturing towards Olivia. Ratigan comments "Oh, you want to lighten the load? Excellent idea." and throws Fidget out of the basket. He shouts these words as he pitifully flutters and finally falls towards the Thames river.
