The much-loved animation series from Ireland’s Cartoon Saloon (Wolfwalkers, Song of the Sea) gets a big-screen spinoff, which will be welcome news for preschool puffin fans and for parents who fancy losing themselves in a gentle, gorgeously animated balm of a film. Minor peril comes in the form of seagulls eyeing an unprotected little egg. But the real threat is climate change in this entry-level eco-parable: Puffin Rock welcomes a community of refugee puffins whose habitats have been ravaged by storms. And, after a few misunderstandings and some egg-based jeopardy, Oona the puffin and her little brother Baba find some new buddies.
