If you loved Penguin Highway, try Rain in the Sunshine
A bridge between a film you've already seen and one most people haven't. Rain in the Sunshine has roughly 15.8× fewer votes than Penguin Highway — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Hiroyasu Ishida, and they both carry the cozy, tender mood tags, and they sit in Adventure / Animation / Fantasy territory. If that's the register that drew you to Penguin Highway, the second film will land in a comparable space — through a different lens.
What Rain in the Sunshine is
A boy who’d sooner turn into a wren than speak up discovers that confessions, like birds, have a way of taking flight. When his classmate departs town, he launches himself after her on borrowed wings. The sky becomes a ceiling too low for his courage, or so he thinks mid-air.
