A 1981 anime based on the book ''Literature/TheSwissFamilyRobinson'', about a family which gets stuck on a tropical island after a shipwreck and have all sorts of adventures there.

While there, they build a huge treehouse. As they explore the island, they find out they're not the only ones stuck there.

Both this and [[Anime/AiNoWakakusaMonogatari Tales of Little Women]] aired at the same time during the late 2000s/mid 2010s when TBN's channel Smile of a Child used to be part of it (This originally aired 10 PM/ 7PM on Mondays, Wednesdays and Fridays, but switched to Tuesdays and Thursdays). It's now released digitally on Amazon.

* DubNameChange: In the U.S. dub, Flone is renamed "Becca". A bit inverted with Fritz: while the Japanese original renamed him as "Franz", the U.S. dub became recursive in naming him back to Fritz to make it more compatible with the original novel.
