Eleven fantastic creatures left their tracks in the snow. Can you identify all of them and the twelfth creature that left no tracks?
Each answer is in the grid in "reading order", starting with the cells I've specified. Cells are (row, column) starting in the top left.
FAUN (3,6) / LAMIA (1,4)
GRIFFIN (5,2) / OUROBOROS (3.2)
HARPY (7,6) / ROC (4,1) / WYRM (1,8)
HELLHOUND (7,1) / WYVERN (1,3)
HIPPOGRIFF (3,4) / YETI (1,1)
And the trackless creature is
a WILL-O-WISP, found in the unused cells.
