Shay Act 1
This is the first trophy that you can get in Shay's story and is missable. When Shay is sat at the table in the kitchen right at the start of his story, refuse every single one of the cereals that are offered by the robotic arm. You'll be offered 11 or 12 different cereals, the last of these being SPLARGH. Once you have refused SPLARGH, the trophy will pop.
