This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Tsurube-otoshi (Japanese)
Tsurube otoshi are a gigantic disembodied heads of either a human, a tengu, or an oni. Sometimes they appear wreathed in flames like large fireballs with facial features. Spending most of their lives high in the trees, they live deep along paths in the forest, or just outside of town where travelers are likely to pass.
Tsurube otoshi range in size from an ordinary human head to up to two meters in diameter. Tsurube otoshi lurk in the treetops late at night and wait for unsuspecting creatures to pass underneath. When they need to feed, they drop quickly to the ground like a stone. This is the reason for its name, which means “falling well bucket.”
