1) Ogerpon (and her trainer) wore masks to not frighten people.
2) If they have no masks it frightens people.
3) Frightened people scream in fear.
4) People need to open their mouths to scream.
5) When they open their mouths they can be force-fed Mochi and become subjugated to Pecharunt and forced to TikTok Dance for its amusement.
6) As the ruler of the domain bejeweled masks are obviously going to go into the treasury, or they can be used to bargain with Ogerpon to make it subjugate itself into another Retainer.
Pecharunt is very smart and definitely not winging it for shits and giggles and i am not pulling this out of my ass. =^]
