Milky Well becomes open after the defeat of Master Belch. Exiting from the factory brings the player on a ledge that was previously inaccessible on the first visit to Saturn Valley. It first enter a straight cave leading to the outside area. On the outside, the path goes through a small valley in an L shape begore going back into the cave. Back inside, it follows a straight path until reaching the Trillionage Sprout at the end.
History
After the defeat of Master Belch, Ness, Paula and Jeff exit onto a previously inaccessible ledge in Saturn Valley. The trio challenge the dungeon after a coffee break. They then trek through the dungeon to find the Trillionage Sprout at the end. After successful defeating it, Ness thinks he hears his mother from far away, saying "be a thoughtful, strong boy...". He collects the melody of Milky Well and returns to Saturn Valley.
If Ness is either unconscious or diamondsized when reaching the Milky Well sanctuary, upon being revived Milky Well will be misspelled as "Milkey Well".
