Toriel's phone is a cell phone that the protagonist acquires from Toriel once they start to go through the Ruins alone. The cell phone offers a small menu of topics to call Toriel about. From this menu, the protagonist can say hello, ask Toriel about herself, call Toriel "mom", flirt with her, or ask for puzzle help if the protagonist is in a room with a puzzle. After the protagonist leaves the Ruins, Toriel will not answer the phone until the end of the True Pacifist Route. Dialogue in this ending changes based on what the protagonist called Toriel about in the Ruins.
