I thought you guys would like to know which monsters those themes belong to in certain areas.

Ruins Field's theme is actually Kechawacha's theme, even though it plays for other monsters.

The Primeval Forest's is Garara Ajara's theme.

Generu Serutasu's theme is the Heavenly Mountain's theme.

Frozen Sea's one is quite obvious. The Frozen Sea's is Zaboazagiru's theme.

The Unknown Great Forest theme belongs to no monsters.
