Return the five lost shroomlings to Mrs. Puffshroom to earn Family Reunion and gain Mushroom Bond. In the full game, its occasional mushroom transformation is temporary. It does not end the game.

Find Mrs. Puffshroom
Go to the north end of Underkeep village. East of the northern exit, look for the path through the foliage. Her NPC marker appears when the party gets close. Bring the lost mushroom children back to her rather than handing them to the merchant.
Choose the recipient
| Return them to | Immediate outcome |
|---|---|
| Mrs. Puffshroom | Family Reunion and Mushroom Bond. |
| The merchant | Gold, food and recipes. The large mushroom becomes hostile on a return visit. |
Mushroom Bond can briefly transform a hero again later. Players report returning to normal after a turn or movement; a transformation is not a permanent loss of the hero’s equipment. Do not restart the run because of the demo’s game-over behavior.
Developer sirrobbo confirms that this choice changes later outcomes. Keep a manual save before handing in the children if you want to revisit the decision. The bond alone does not establish every later dialogue or rebellion requirement.
