Eureka, Carl The Sheriff's Jeep

original movie prop

In fourth season special holiday episode Do You See What I See, the town of Eureka and all its inhabitants are turned into cartoon versions of themselves, in shifting animation styles.  During the claymation sequence, Carter has to come to terms with his disgruntled car (who wants more appreciation), before they head off to the rescue with 'Carl' careening through the snow after transforming his tires to skis.

Custom detailed toy Jeep Cherokee, with skis, decals matching Carter's real-world vehicle, and mini figures of Ranger Jack and Princess Jo inside.
