Board notes 5 details
- Layout
- Tiki stands beside a partly lifted manhole with eyes underneath; Bubba waits by a teal bin, and the left restroom door shows a pink female plaque over a hidden blue male sign.
- Goal
- Divert Bubba into the correctly marked restroom, then uncover Larry beneath the black sewer lid.
- Opening
- Slide the pink women's-room plaque sideways to expose the blue men's-room symbol behind it.
- Danger Zone
- The bin is a decoy, and dragging Bubba does not solve the obstruction; reveal the sign before lifting the manhole cover.
- Mechanics
- A layered wall sign changes an NPC's route, clearing access to a second hidden-character reveal.
