Gramophones are key items in Hello Neighbor that were introduced in Beta 3.
When a gramophone is interacted with, it plays music. This music is used in cultivating the tomato plants that appear in various areas of the Neighbor's house. The plants either grow or wilt depending on which gramophone is played near them.
There are two gramophones in Hello Neighbor. One of them is a gramophone with a green record which plays the Alpha 2 intro theme, and grows the plants. It can be found on the balcony outside the day/night door rooms. The other has a red record which plays the Pre-Alpha and Alpha 1 chase theme, and wilts the plants. It can be found in the flooded room at the top of the tall ladder, and can be reached by solving the frozen globe puzzle.
