The three main characters are: the Cat, a hungry alley cat who initiates the chase by planning to eat the canary; the Canary, a frail but resilient bird who becomes a giant after being exposed to the growth formula; and the Mouse, a street-smart creature who acts as the voice of reason and grows to a colossal size. All three end up in a frantic competition to see who grows biggest.

The canary is the frail but resilient protagonist who enters the cat's world of hunger and danger. Small and vulnerable at first, she holds her own through quick thinking and occasional bold moves. After being subjected to the Jumbo Gro growth formula, she becomes a giant and uses her size to resist predation and survive the escalating chase.

Deception propels the plot as the cat tricks others to get food and avoid danger. The mouse uses sly reasoning and warnings to guide survival, and their schemes generate tension and humor as each tries to outsmart the other. A meta twist shows the characters know they are in a cartoon, adding a playful layer of self-aware deception.

The film uses scale as a satirical mirror for ambition and control. The cat's initial plan to enlarge his food reflects petty self-interest, but as the formula spreads, the characters' ambitions grow beyond their surroundings and eventually beyond the world itself. The ending suggests that unchecked experimentation leads to absurdity rather than satisfaction.
