Mochi Mayhem

Spoiler warning: this article may contain major plot or ending details.

After interacting with a decoration at Peachy's, the player receives a phone call from Arven, asking if he can visit the player at their house at Cabo Poco. During the conversation, the decoration disappears from behind the player's back. Upon returning home, the player meets Arven, along with Nemona and Penny, who had overheard his phone call and insisted on coming along. The player's Mom gives the player a letter from Kieran, informing them that he's taking a break from Blueberry Academy and is currently residing at his home in Mossui Town. The letter also includes tickets for the player and their friends, who are all feeling happy about the idea of getting to visit Kitakami, so they depart there immediately.

In Mossui Town, Nemona, having learned that Kieran used to be the Champion of Blueberry Academy, is quick to challenge him to a battle, and defeats him soundly before the player even has a chance to come see their match. Just then, Carmine shows up, performing a weird dance and repeating the word "mochi" over and over. Kieran explains that she's been acting like this ever since he sent his letter to the player. He suspects that his sister's odd behavior might have something to do with a curse that's rumored to be going around, but the group encourages him to stay positive. The group retreats to the Community Center for the night, but while they search for a hidden TV remote, Nemona suddenly disappears. When the player and Kieran go look for her, they find more villagers acting in the same strange way as Carmine. Spotting Nemona, they follow her to Reveler's Road, where they witness Kieran's grandfather Yukito falling victim to the strange behavior as well after eating some suspicious mochi offered by his already-possessed wife, Hideko.

After defeating Yukito and Hideko, the player receives a phone call from Arven and Penny, who have been holding out at Peachy's. When the player and Kieran return to Mossui Town, they spot a strange Pokémon, who also possesses Arven and Penny by firing pieces of mochi directly into their mouths. The player and Kieran avoid the mochi and face their possessed friends in a Multi Battle. Afterwards, they pursue the mysterious Pokémon to Loyalty Plaza, where they also find Nemona, who has also been possessed. With a horde of possessed villagers approaching them, Kieran holds them off while the player battles Nemona. Once she has been defeated, the player challenges the mysterious Pokémon, identified as the Mythical Pokémon Pecharunt, defeating and catching it. This releases everyone from Pecharunt's control, with only vague memories of what they did while possessed. After spending some more peaceful time in Kitakami, the player and their friends return to Paldea, while Kieran and Carmine return to Blueberry Academy.

The player is required to battle Pecharunt after defeating Nemona whilst she is under its influence. It must be caught upon its defeat, and is coded to never be Shiny. It has set Timid Nature when caught.

The player is sent back to the Pokémon Center if they black out during this battle, and they can challenge Pecharunt again.

	Types: Poison Ghost Tera Type: Poison  or  Unknown Ability: Poison Puppeteer Held item: None
Pecharunt Lv.88
Nasty Plot Dark Status   --       Toxic Poison Status   --       Malignant Chain Poison Special   --       Shadow Ball Ghost Special   --

The picture used in this section is unsatisfactory. Please feel free to replace it so it conforms to Bulbapedia conventions. Reason: Needs higher resolution, direct feed screenshot of Ogerpon

Ogerpon's reaction to seeing Pecharunt

• Mochi Mayhem is the only occasion in Pokémon Scarlet and Violet in which the player has a Multi Battle against two separate opponents.
• Although it is never shown to the player in-game, all of the Pokémon owned by Aya, Shige, Yukito, and Hideko are programmed to have Poison as their Tera Type, likely as a reference to the effects of Pecharunt's Binding Mochi.
• In the Japanese version, the possessed shout out "Kibi kibi!" rather than "mochi", referring to kibi dango (millet dumpling) from the folktale of Momotarō.
• If the player uses Ogerpon in the battle against Pecharunt, Ogerpon will react with anger, yelling out "GRAH! Pon PON!!!" at it, likely for what it did to Ogerpon and its companion in the past.
• If the player uses a member of the Loyal Three (Okidogi, Munkidori, or Fezandipiti) in the battle against Pecharunt, Pecharunt will react with shock and anger, yelling out "Pechaaa! Chraaahhh!" at it, likely for its betrayal as Pecharunt's retainer.
  • Pecharunt will repeat this reaction every time a member of the Loyal Three is sent out for the first time by the player.
• The day that Mochi Mayhem was made publicly accessible is the same day as the annual Japanese tradition of mochitsuki (Japanese: 餅つき).
• Mochi Mayhem shares a number of similarities to the dancing plague of 1518. They both:
  • Involve a mass outbreak of spontaneous, uncontrollable dancing.
  • Were started by a single woman, who was afflicted much earlier than anyone else.
  • Were caused by food poisoning (Binding Mochi in the case of Mochi Mayhem, and theorized to be ergot in the case of the dancing plague).
• During the events of the DLC, the Pokémon Center attendant outside the Community Center remains unpossessed and has dialogue regarding the "curse".
• Pecharunt's shadow can be seen moving in the background when the title card is shown.
