What’s it about?
The story.
Jim the chimpanzee wakes up in a terrible mood, and he has no idea why. The birds are singing, the sky is blue, and everything in the jungle is beautiful, so why does everything feel so wrong? His well-meaning friends line up with advice: smile, jump around, eat a banana, cheer up. But the more they try to fix him, the grumpier Jim gets, until he finally has a proper meltdown and realises the truth: sometimes you just need to feel your feelings and have a grumpy day. Suzanne Lang's deadpan text and Max Lang's expressive, comic animal cast turn a universal childhood mood into something genuinely funny and quietly liberating. A gentle, hugely popular introduction to emotional literacy, it reassures children (and the adults reading it) that all feelings are allowed, and that a bad mood will pass in its own time.

Right for your child?
Where it lands by age
A read-aloud for roughly 3 to 6s, with humour and a gentle emotional-literacy message that adults enjoy too. Early readers of 5 to 7 can manage the short text, but it shines as a shared read for talking about feelings.

Why it lands
Why they love it.
Why kids love it
Jim is in a foul mood and everyone keeps telling him to cheer up, which is deeply relatable. His big meltdown is very funny, and the reassuring ending, that you are allowed to just feel grumpy sometimes, lands perfectly for children learning about their moods.
- Being understood finally
- Friendship and belonging
Why parents love it
A genuinely funny way to tell children that all feelings are allowed and moods pass. The deadpan humour keeps grown-ups smiling on repeat reads, and it hands you the words for talking about bad moods without ever preaching.
- Shared humour
- Conversation starter
- Bedtime appropriate
