Kelvin the frog is hopping on the coordinate plane \mathbb{R}^{2}. He starts at the origin, and every second, he hops one unit to the right, left, up, or down, such that he always remains in the first quadrant \{(x, y): x \geq 0, y \geq 0\}. In how many ways can Kelvin make his first 14 jumps such that his $14$th jump lands at the origin?
