The Lego minifigure scarecrow from the Lego Arkhum Asylum Set #7785/7786 is definitely that one. This rare little figure sells between $10.00-$45.00 depending on condition. They also have a GREAT sell through rate.
It would definitely be worth your while to research “Lego Minifig” or “Lego Minifigure”. There are quite a few that are worth some good money.
Hope you can “snap” one up!
