Tails, Sonic, Knuckles, and Amy meet Perci outside her house near the gate of the unnamed village. Perci is concerned with the village's safety while being frustrated with the other villagers caring less about such, focusing on the mayor's re-election. Tails affirms he and his team will stop Lyric from invading the village. She is reluctant at first, but lets them prove their worth by energizing monuments to strengthen seaside defenses on the Bygone Island. After the team finish this side mission, the bandicoot rewards them with a Power Glyph of the player's choice, and promising them to a toast of victory after Lyric's defeat at the end of the game's story.
In "Battle of the Boy Bands", Perci was one of the brainwashed Justin Beaver fangirls obsessed with his mind control music. She attended a Justin Beaver concert in which Tails' band, Dreamboat Express, challenged him to a sing-off. Perci and the other fangirls were freed after Sonic used a counter-frequency on Justin, then cheered on Tails' band under a new name, Dude-itude.
In "Fire in a Crowded Workshop", Tails went inside his smoking workshop and saw Perci, Sonic, Knuckles, and Amy covered in soot. Sonic tried to explain his own version of the story of how the workshop caught fire. Knuckles disagreed with his version, then told his own version. Amy likewise disagreed with Knuckles' story then tells her own. Aggravated by the contradicting points of view, Perci told her own version of the story that Sonic, Knuckles, and Amy were equally fretting over the accident. Tails revealed to them that accident was caused by his new security system that should have gone off. Resolved, Sonic, Amy, and Knuckles went out to eat at Meh Burger, leaving Tails and Perci the only ones inside the workshop. As Tails fixed Perci's bicycle she said in a flirty manner, "I like a guy who's handy." Tails opened his welding mask and blushed.
In "Muckfoot", after Tails' discovery brought Muckfoot mania to the village, Perci praised him for the effort. During "Three Men And My Baby!", Perci, Staci (her twin sister), and Zooey glanced at the passing Sonic, Tails, and Knuckles who are feeding Lady Walrus's younger son Chumley.
