[edit] Speculation

A Woodsy Owl is a unit. Its appearance and stats are not known yet.

A Woodsy Owl is likely to be one of the unit types used by Ad Council.

A Woodsy Owl probably has a sonic attack, in the form of a "Hoot". Perhaps it cleans the adversary by sonically causing their weapons to disappear.

A Woodsy Owl likely has the Fly special, and is likely forest capable as well.

[edit] Real World References
