The Mini Bobble Head Comical Ram or Bighorn Sheep is seated upright on a patch of grass. The Bobble Head is approximately 7.6cm tall. The mini bobble head of the Ram is spring activated, when the Ram is moved the Bobble Head begins to Nod and that is why you will sometimes see the word Nodder. The Mini Bobble Head Comical Animal is a collectible item and is not appropriate for small children. This new Comical Mini Bobble Head would be a great addition to your collection of animals and/or Bobble Heads. Did you know. Rams compete for females in late fall, and rivals sometimes get into head-butting contests. After walking apart 15 to 20 yards, the two rams turn, rise up on their hind feet, then drop to all fours and race toward each other. The clash of their horns can be heard more than a mile away. Collisions may be repeated, but eventually the contest becomes a matter of pushing and shoving, until the stronger, heavier ram drives off the weaker one.
