The Sumikko go on a camping trip to the Sumikko lake where the mysterious lake creature Sumisshi lives. Sumisshi is a dinosaur and Tokage's mother, but that is kept secret from the other Sumikko. They end up never meeting Sumisshi. Back home, the Sumikko are outside looking at the moon, when a group of wizards arrive from the sky in a magic glowing boat. (Source: Wikipedia)
