Ep. 21: Chacha and friends search for Sorges and the stamp at a mixed-gender onsen.

21

Chacha, Riiya, Mr. Rascal, and the Principal track Sorges and a missing stamp to a mountain onsen after helicopter wreckage is found. Sorges, injured, plans to return the stamp once healed. The group encounters Seravy and Dorothy, joining them at the mixed-bath facility where everyone wears swimsuits. They meet the bandaged Sorges but do not recognize him. The innkeeper Beppu attempts to eliminate Chacha by causing a ceiling collapse that also crushes Sorges. He then traps the children in a bungee basket over boiling water, kidnapping Marin and Orin. Beppu transforms into a giant clay statue to attack the pursuers. Riiya overcomes the sulfur scent to locate the trail. Chacha transforms into the Magical Princess to defeat Beppu. Seismic activity erupts, scattering the group as they search for the stamp, which Sorges drops and is launched into the sky by a volcanic eruption.
