Chapter 2 walkthrough: science building
Chapter 2 is five science rooms. The earliest bird in Coop de Grace is the Clue Jay, not a character named Nugget. Food-chain codes in the write-ups are 9631, 9642 and 9753.

What the science rooms actually ask
GameSpew and ShowGamer both name Scientific Method, Coop de Grace, Memory Leak, Overengineering Class and Lightbulb Moment. The animal line is cheetah, octopus, howler monkey, tortoise, whale. Memory Leak’s element reading is 18826 from argon 18, oxygen 8 and iron 26, the hazard tag is 403, and the molecule is written CH5NO3. I am not smoothing those into a single “science code.” They belong to different benches.
Lightbulb Moment is the room the 7 Nov 2026 patch called out: the first time you load it, the marbles had no physics. The published codes around that room are 5423 and 2468, with trampoline readings 895, 658 and 986. The POTENTIAL color key in GameSpew is U yellow, double-equals orange, M red, G light blue, H purple. If your marbles still fall through the track, that is the bug the patch described, not a new solution.
Players searching for a bird puzzle are in Coop de Grace. I kept the anchor on this page because splitting a second URL would answer the same room twice. Nugget shows up later as a nest in the red-herring list, which is a different object.
