A fifth episode that sends the Bad Guys into space with rockets, aliens and a lot of toilet humour. It is broad, silly and highly readable, especially for children who want jokes and action more than realism.

What’s it about?
The story.
The world is ending, which is bad news. The good news is that the Bad Guys are ready to save it, or at least they think they are. Their plan involves borrowing a rocket, heading into space and trying to deal with a disaster that quickly becomes much bigger, stranger and smellier than expected. Intergalactic Gas expands the series from animal rescue and comic villains into full sci-fi absurdity, with aliens, rockets, spacesuits and the sort of body-humour jokes that many seven-to-ten-year-olds find irresistible. The structure is still short, punchy and heavily visual, so even though the stakes are technically enormous, the reading experience remains light, silly and accessible. It is a strong match for children who like Dog Man, Captain Underpants and chaotic adventure comics, particularly those who enjoy space settings when they are played for laughs rather than serious wonder.

In the classroom
How it works in school.
The wildly funny Bad Guys series — a legendary reluctant-reader hook and classroom-library staple.
A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.
Why it lands
Why they love it.
Why kids love it
The specific delight is fart jokes at industrial scale — Marmalade's intergalactic-gas plan involves Mr Piranha in ways only Mr Piranha can be involved, and the toilet-humour quotient hits its series peak. A seven-year-old gets the rocket adventure plus the silliest body-humour the series offers.

- Making a difference
- Surviving danger
Why parents love it
The Bad Guys for the kid who came specifically for fart jokes — the toilet-humour ceiling of the series, played at full volume. Rocket and space premise gives Blabey room for new visual jokes. Reliable mid-series; nobody will be confused about what they're getting.
- Shared humour
- Quick to read
- Conversation starter
