Paul Terry's Mighty Mouse Comics #40

In "The Hoodlum Gang," a baby mouse stolen from Mouse-Town and raised in Cat-Town by The Claw and Professor Ohm grows up to become Mugger Mouse, a hardened juvenile delinquent sent back to corrupt the next generation. As crime spreads through Mouse-Town and even the young mice turn their backs on justice, Mighty Mouse faces his toughest challenge yet—not in a battle of strength, but in a war against the apathy and rebellion of youth.

In "Underground Tyrants," Mighty Mouse races against time to free his fellow mice from a hidden mine beneath Clawville, where they’re enslaved by The Claw and forced to dig a dangerous explosive ore. With the help of a brave little mouse named Runt and a skeptical "railroad dick" cat, Mighty Mouse must navigate a cat-dominated city that’s all smiles and secrets—where every friendly face hides a threat, and the truth lies deep underground.

In "Duel or Snow Duel," Mighty Mouse and Oil Can Harry clash in a frozen showdown at the North Pole, where Harry has imprisoned Pearl Pureheart in ice and the hero finds himself struck by a powerful bolt of lightning—leaving both their fates hanging in the icy air.

Shamus the Leprechaun tends to the whimsical charms of an Irish woodland village, weaving luck and kindness into everyday life. When No Good Bear unleashes his dark magic to grow into a monstrous threat, the peaceful forest trembles—forcing the clever leprechaun to stand against a fury he never expected.

When the peaceful mice of a tropical island are terrorized by the myth of Kuloo The Powerful, a fearsome mountain god demanding daily sacrifices, the arrival of Mighty Mouse disrupts the illusion. Black Mike and his hench-cat have been exploiting the islanders’ fear for months, but now the heroic mouse must face a threat more cunning than claws—manipulating belief itself.

Farmer Gray tries to pull up a stubborn tree stump using his horse, but the chain snaps mid-effort. Enter Dimwit, who offers a clever — or at least unusual — replacement for the broken chain.

In "Lights, Action, Camera," Sourpuss takes on the role of director and star in his own movie, determined to prove his artistic flair—only to be upstaged by Gandy Goose’s accidental genius when the camera, meant for a scene, captures a real-life robbery and helps bring the crooks to justice.

When fiery lava men erupt from newly formed volcanoes and begin conquering both Mountain Village and the Claw Territory, Mighty Mouse faces a threat unlike any he’s encountered—literally too hot to handle. With the citizens of both mouse and cat communities in peril, the hero must find a way to stop these molten invaders before they consume everything in their path.
