About Us
Grandpa Grimm's KneeKnocker Woods was brought to life by the owners and family of Icon Poly, a custom 3D sculpture fabrication company.
Located in rural Nebraska, just west of Gibbon on U.S. Hwy 30, the outdoor animatronic Halloween experience is set along an old wooded river which snakes through corn planted agricultural land and features an unsettling stroll through the creepy woods to the place of an abandoned zombie infested community, complete with a graveyard and many other modified community attractions and services. It's like they are building their own town out there.
This experience uses state of the art amusement park quality animations to entertain at a level rarely found in an outdoor Halloween attraction.
