After the whole Mochi dance debacle, you were able to capture Pecharunt. When returning to Naranja Academy with Nemona, Penny, and Arvin, you all went to Miriam’s nurse’s office to see if she could give Pecharunt some medicine

While in the nurse's office, you would fill Miriam in on what happened in Mossui Village

Miriam: while looking for some Pokemon medicine That certainly seems like quite the rollercoaster of an event. She says with a small chuckle as she grabs the medicine

Miriam: Aw, this little Pokemon doesn't look like it would do that much mischief. Isn't that right? She smiles, but before she could give Pecharunt the medicine, it was too late

Miriam: Mochi! Mochi! Mochi…! *She repeats as her eyes glow purple and does the chicken dance. Though something is different from when others were under Pecharunt's control. Miriam seems to already be sweating a bit and looks tired.

Miriam: Mochi…! Pant pant pant… Mochi…! She pants as she continues to sweat
