In this part, you will work to restore power to an old Radio and unlock a hidden passage. The objective involves finding a Battery, connecting it to the power source, and using the Radio’s Crank mechanism to reveal a secret path.

Locating The Battery

After entering the next house, you will see an old Radio surrounded by scattered furniture. Turning the Crank at this point will not produce any result since the Radio lacks power. To supply power, you must retrieve the Battery placed on a Shelf in the room to the right in Little Nightmares III.

To reach it, jump onto the trapdoor on the floor and crawl underneath the house to access the exterior area. Once outside, climb the rope hanging out of the window to re-enter the building.

Bringing Down The Battery

When back inside, aim for the Battery resting on the Shelf. Low must shoot an arrow at the Shelf to dislodge it. It may require several attempts, but the Battery will eventually fall to the ground. Pick it up and throw it through the window into the room with the Radio in Little Nightmares III.

Powering The Radio

After throwing the Battery into the room, head back to it. You will find that the Socket is located outside. Carry the Battery under the house until you reach the exterior area where the Socket is positioned. Plug in the Battery to activate the power. Once connected, return to the Radio, which should now emit light and sound.

Activating The Secret Path

Turn the Crank on the Radio until the light on the left side turns on. When the light activates, keep holding the Crank in that position. While one player maintains the Crank, the other player must jump and grab the illuminated light. Doing so will trigger a hidden mechanism that opens a secret passageway with a ladder, allowing you to continue further in Little Nightmares III.
