Nobody talks about this one. A tiny OVA from 1994 where Keroppi and friends help an injured migrating bird complete its journey, and it works because the show refuses to make it bigger than it needs to be. The heart lives in the specificity: a real problem, a practical solution, kids doing what kids actually do when they see something hurt. It costs almost nothing to watch. It gives back everything.
Keroppi and his friends are playing with a kite when a bird on its seasonal migration gets hurt. Hoping to see it finish the long trip, the gang goes to a local pilot and asks for help. This single-episode OVA from 1994 is a small adventure built around the friends coming together to aid an animal in trouble.
