- Japanese episode title: ドギマギ! うち 記憶喪失に なっちゃった!? (Dogimagi! Uchi kioku soshitsu ni nachatta!?)
English translation: "Flustered! I've Lost My Memory!?"
Original airdate: May 21st, 2012
Himespetchi thinks Prince Tamahiko is her crush rather than Mametchi due to her having amnesia.
This episode contains the following tropes:
- Amnesia Episode: For Himespetchi, at least in part. She regains her memory, but at the same time Tamahiko loses his memory, halfway into the episode.
- Call-Back: When Himespetchi remembers Mametchi is her crush, she remembers a scene from the end of episode 126 where she and Mametchi ride a ferris wheel. She and Prince Tamahiko are about to board the same ferris wheel when Himespetchi panics from her realization.
- Easy Amnesia: Himespetchi gets amnesia from tripping on stairs. Prince Tamahiko gets amnesia when Himespetchi hits him by accident.
- Ferris Wheel Date Moment: Subverted. Himespetchi and Prince Tamahiko go to ride a ferris wheel together, but Himespetchi regains her memory and freaks out when she remembers her crush is Mametchi.
- Here We Go Again!: The episode ends with Prince Tamahiko having regained his memory... but with the other Tama-Friends developing amnesia in the process.
- Injury Bookend: While Himespetchi only needs to see the ferris wheel to realize she rode it with Mametchi before, Prince Tamahiko doesn't regain his memory until he's hit during an incident with some bouncing balls in the Gotchi King's castle.
- Romantic Spoonfeeding: Himespetchi and Prince Tamahiko see Tamagotchis spoonfeeding their loved ones desserts while on their date.
