The long opening credits may throw some younger viewers off track at first. On the other hand, there is a catchy tune that invites even those unfamiliar with Japanese to sing along. Familiar Heidi vibes in terms of illustration, with no common thread in terms of content, but rather a colourful one. I would almost say that what is shown is pretty weird, but all this craziness is wonderfully entertaining and endearing. A format for young and old, it feels like a precursor to later Ghibli works such as Totoro. The full-throttle mode that's used here is cancelled out by the pleasant running time. A little secret treasure that should definitely be discovered!
