Natzu

Natzu Prairie is an area in The Legend of Zelda: Oracle of Seasons. It is roughly in the center of the map, with Goron Mountain and the Temple Remains to its north, Holodrum Plain to its west, Horon Village and Eyeglass Lake to its south, and Moblin's Keep to its east. Its terrain will actually take one of three different forms, depending on which animal companion Link ends up with.

The area
No matter what the terrain, certain aspects of the area will always remain the same. Blaino's Gym will always be found one screen south of the sign advertising it. Additionally, a Scent Seed Tree will always be found one screen west of the sign advertising Blaino's Gym.

Ricky
If Link gets Ricky as a companion, the terrain will be filled with prairie-like greenery and high ledges. Due to the nature of the terrain, Link must use Ricky to navigate much of the area.

Moosh
If Link gets Moosh as a companion, the terrain will become a wasteland. Rocks and long lines of pits will fill the area, making the it impassible to traverse without Moosh, even with the help of the Roc's Cape.

Dimitri
If Link gets Dimitri as a companion, the terrain will become filled with waterfalls and swift-moving waters. As with the other three versions of the area, it is impossible to navigate the area without Dimitri, even after acquiring the Zora's Flippers. If Link jumps in the currents without Dimitri, he will be unable to swim against it and will be taken wherever the current leads him.
