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 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 animatronics to entertain at a

level rarely found in an outdoor Halloween attraction.
