Nisos and Gregor run to get the goblin corpses, while Saucix and Adarim pull Gerald through the door and slam it shut. The three of them put their weight to the door, to keep it closed until Nisos and Gregor return. The mink pushes frantically from the other side.

The mink leaps into the door from the other side. The impact throws Saucix and Adarim onto their backs, but Gerald stands fast and keeps the door sealed. Nisos and Gregor return with the goblin corpses, placing them before the door, and Gerald carefully lets it swing open. The party retreats as the mink jumps through the doorway, spots the corpses, and hungrily starts tearing into them.
