The Blob Is Controlling The Boy
If you couldn’t tell already, we’re going to be talking a lot about mind control, so here’s another one from the Steam forums. This theory says that the blob is one final misguided experiment on the human’s part to perfect the mind control technology they’ve been working on.
Through these experiments the blob becomes a sort of hive mind, with the ability to propel its consciousness onto other beings. Because of this the blob has taken control of the boy in an effort to break itself free from captivity. It could also explain why a small child shows absolutely no fear in the face of such dangerous and freakish events. By collecting hidden spheres throughout the world, players can also unlock the game’s secret ending. In it the boy discovers a secret bunker with a strange device, and a giant plug inside. By solving a quick puzzle, players have the option to pull out the plug. By doing so, the boy slumps into a zombie-like stance and the screen fades to black. This could show the boy knew he was under control, and was searching for a way to break free.
