Full spoilers — story, solutions, facts and questions
In the late-game FEAST scene, take the leg when the TV prompts you, then use the valves to open a continuous route through the body shown on the monitors. Feed Curly only after setting the route. The written instructions here come from one community chapter guide; an exact valve-by-valve rotation sequence has not been independently verified.
What I saw
This guide compares public written sources checked on 2026-10-28. No gameplay test was performed. Specific details supported by only one source are labeled below.
Use the monitors to check the route
The chapter guide describes six monitors showing sections of the digestive route. Turn one valve and watch which section changes. Work through the sections so the passage is open, then attempt the feed. This is a single-source description, not a tested rotation sequence.
According to that same guide, an incorrect route makes the food stop and Curly reject it. After a successful feed, it reaches the stomach and the monitors turn to static. No numbered rotation count or starting orientation is verified here.
Set the Mouthwashing feast valves
- Take the prompted item. When prompted by the TV in FEAST, take the leg. The chapter guide is the sole source for this sequence.
- Watch the monitors as you adjust. Turn the valves to open the route shown on the screens. Check the effect of each adjustment; no fixed rotation count is verified.
- Test the feed. Once the route is open, feed Curly. The guide describes rejection for a blocked route and static on the monitors after success.
