A hidden task-based guild whose entrance exam is to successfully sing a listed song onstage.
The Stage Performance Guild is one of floor ten's secret task-based guilds, its door hidden inside the Lollipop bar and openable only by passing a live entrance exam: sing one of the listed songs onstage well enough to fill a performance gauge. Some listings are duets scored on two separate gauges, so a pair can enter together — or only one may succeed. Carl targets the guild as part of his layered escape scheme, singing A-ha's 'Take on Me' as a duet with Princess Donut while a Dwight-triggered bar brawl rages around them.
Fortified by Mordecai's compounded singing potions and the Gelded Choirboy scroll, Carl nails the extra-high note and is granted permanent access; Donut, despite max Auto-Tune, FAILs her line when a paralyzed Dekoki falls into her. Completing the exam also unlocks a standing reward: hidden guilds with entrance requirements now appear on Carl's map whenever he is near one.
A glowing, pulsing secret door set into one bar wall — the only wall left unscorched after the brawl's fire.
A hidden performance guild Carl enters as a rung in his floor-escape plan, its map-revealing reward exposing every other nearby hidden guild.
