Pulling for the Plushie!

Pulling for the Plushie! is the eighth episode of the series. It's an episode of Sports Science with Ruff.

Plot
It's revealled that the truck full of kibble with the plushie went to the county fair. Now, with Grandma Ruffman's birthday only two days away, Ruff and Chet are informed by Glen that the kibble is for the annual llama pull, where each contestant rides a llama as it pulls 200 pounds of kibble over either sand, grass or pavement and the contestant that travels 50 feet the fastest wins all that kibble. That's when Ruff realises that he has to win to get the plushie back.

The llama Ruff is riding is an unfriendly one called Steve, and he charges over all three surfaces. Blossom points out Steve moved more slowly over a different surface. If Ruff picks the right one, he'll win the kibble (and get his plushie back)!

Two kids call Ruff on his iBone and offer to help. They have everything they need for the challenge: a sled, kibble, and a strong girl named Jade for the llama. They make sure the kibble goes the same distance as the other surfaces. It takes 12 seconds to go over the grass and sand takes 15. But pavement only takes 8 seconds, making it the fastest surface.

Ruff learns that pavement was the easiest because of friction. Blossom and Glen tell him that when two surfaces of objects push and pull against each other, it slows their motion, thus creating friction. There was less friction on the pavement.

Ruff picks pavement for Steve to walk across and the dog wins the race! He buries through the kibble and finds the plushie, but Steve runs off with it.
