Walks are important for getting a character from point A to point B. It takes some practice to animate a walk properly. Today, TV animation will animate the character taking a step and then cut to a tighter shot of the character from the waist up. The character now can bob up and down as the background pans behind them creating the illusion of walking motion.

Here's a series of walk positions where the character is getting smaller as he is walking away from us. This is a complete 2 step walk which can be repeated and reduced in size to link up to the previous walk series.
