With six and a half hours until level collapse, Carl, Donut, Brandon, Chris, Yolanda, and Imani enter the borough boss chamber. Carl reflects that the latest Dungeon Crawler World episode ignored them again, showed other groups already camping by stairwells, and revealed the crawler count has fallen to 2,552,085. Agatha unexpectedly follows the group inside with her shopping cart, and the gate seals behind them.

The arena transforms into a rave-lit maze as walls sink and shift. The boss is revealed as the Ball of Swine, a level 15 borough boss made from at least thirty tuskling aristocrats fused into a massive rolling sphere. Because the music masks the boss’s vibrations and the walls redirect its path, Carl orders the group to run while dropping spike strips made with fragile enchanted shuriken.

The original plan becomes harder when the shifting maze forces the group deeper, but Imani spots a solid open square without grooves. Carl confiscates Agatha’s shopping cart to make room and orders the others to assemble their portable fortress, a modular angled barricade built from goblin tables, weight equipment, braces, and barbell poles. Because Agatha adds an extra body, the group cannot install the final center support before the boss arrives.

The Ball of Swine slams into the redoubt and wedges between the structure and the ceiling as Carl hoped, but the impact knocks supports loose and threatens to crush everyone. Carl, Imani, and the others stab upward through the collapsing frame while Donut warns the boss is overhead. Carl’s shuriken spear finally triggers a decisive rupture, and the ball pops apart into individual tuxedoed and formally dressed tusklings.

The collapsed fortress drops tusklings and wreckage onto the crawlers. Donut fires magic missiles until her mana runs low, Carl uses his upgraded spiked gauntlet to kill disoriented tuskling knights and courtesans, and the shuriken-covered tabletop continues dealing escalating damage to enemies caught on it. Carl realizes the tusklings appear confused victims of the dungeon’s summoning, but because they are hostile, nonhuman, and blocking survival, the crawlers continue killing them.

With the internal walls retracted, the arena opens into a huge purple-lit field. The stairs are visible at the center behind a red forcefield, and Carl understands the remaining tusklings must be eliminated to drop it. Though the tusklings outnumber the crawlers, they are unarmed, disoriented, and quickly slaughtered.
