The Big Boys Club

Three big kids from the top year, jackets stitched "BIG BOYS CLUB." A leader and two flankers. Once a run, they corner you in a hallway — and for the first and only time in the game, Grump is on your side.

Spoiler warning. This page describes the full cutscene, script included.

Trigger conditions

Happens exactly once per run, on day 2 or 3 (decided randomly, 50/50, at the start of the run), always before Grump turns on day 4. Beyond the day requirement, it needs: the day phase active and Grump not yet turned; at least 35 seconds into the day and at least 54 seconds of day remaining; you not dead, downed, hidden, or carrying a toddler; no overlay open, no one currently speaking, and the Card Kid encounter not active; you standing in a real room that isn't your own classroom. Even once every condition is met, it only has an 8% chance to actually fire in any given second-long check — so it triggers "soon after" you become eligible, not the instant you do.

How it picks where to happen

The game searches in a circle around you for a direction with at least 3 units of clear space ahead (room for the three bullies to walk in and flank you) and at least 2.5 units clear behind (room for Grump to arrive from), picking the option with the most combined clear space. If nowhere around you qualifies, the scene simply doesn't start that check.

The scene, beat by beat

TimeWhat happens

Consequences

Local, like the Card Kid

Like the Card Kid encounter, this is entirely local — every player gets their own version, with a stand-in Grump for the scene while the real one is hidden. In co-op, a joining player's Big Boys Club moment still lowers the shared, real Grump's resentment by 20, reported to the host.

Interactions with other systems. While the scene plays, Mrs. Honeywell's dark-classroom nag is suppressed, and (playing alone) the real Grump AI pauses rather than continuing to simulate off-screen.
