- Japanese episode title: ピンチ! ごっち大王ゆであがる!? (Pinchi! Gotchi Daiō yudeagaru!?)English translation: "Pinch! Gotchi King Is Boiling!?"Original airdate: July 9th, 2012
The Gotchi King has come down with a sickness that makes him hot to the touch and gives him strange flower-like designs on his shell. Mametchi and his friends get help from the Gotchi King's old pal Adobentchi to explore the caves of his castle and find the Crystal Crown, which can cure the illness.
This episode contains the following tropes:
- Booby Trap: Adobentchi accidentally sets off three booby traps in the temple portion of the area beneath the castle. The first drops what looks like a washtub on him, the second is a trip rope that makes him stumble into a trap door, and the third sends a boulder rolling at him and the rest of the gang.
- Crystal Landscape: The caves under the Gotchi King's castle have quite a few crystals in them.
- Riddle of the Sphinx: Sphinquiztchi asks the riddle "What has four legs in the morning, two in the afternoon, and three in the evening?" to Mametchi and his gang. Mametchi very nearly answers a Tamagotchi before remembering that not all Tamagotchis have legs and changes his answer to a human.
- Riddling Sphinx: One named Sphinquiztchi is in the underground temples below the Gotchi King's castle. He looks somewhat like Kuchipatchi.
- Sick Episode: The Gotchi King getting a boiling-egg illness is what triggers the plot of the episode.
- Swiss-Army Tears: When the gang finally makes it to the part of the caves that is supposed to contain the Crystal Crown, they notice it's not there. Princess Tamako sheds a Single Tear that falls into the lake below her, which magically causes the Crown to appear.
- Verbal Tic: Adobentchi ends his sentences with "-bencha".
