Magnet Hill is the fifth Your Sanctuary location. It is located underneath the Dinosaur Museum in Fourside
Magnet Hill only appears in Earthbound. It is a small, glowing pyramid above the sewers of Fourside. It gives Ness and company the fifth Melody.
The memory Ness has here is seeing a baby bottle. Beside the hill is a Carrot Key, which is used to get to Pink Cloud.
