When Wheelz, the itsy-bitsy, teeny-tiny "bunny wabbit" got bitten by another rabbit, he became paralyzed. When he was found, nearly frozen in a barn, he couldn't move his hind legs.
Lucky for Wheelz, he had some humans ready to help nurse him back to health. With a $1 miniature skateboard, his humans made an improvised wheelchair that helped Wheelz regain his mobility.
And, as the video states above, "that's when Wheelz got his wheels!"
