Look at the cat that follows your mouse-pointer. it leaves behind a trail of clones. The spinning cat (spinning around the center) click the "see inside" button click into the Spinning cat (around the center) sprite and you see its not changing the direction in the direction box. The cat that moves on arrow clicks will be thought using if statements but click the "see inside" button to see how it actually works. The cat that inflates is thought to have complicated animations but actually, it only uses one if else statement.
