A penguin has to waddle across the whole ice sheet. Writing 10 move lines is slow. A for loop says: 'do this 10 times' in one line.

The loop counter i isn't just for counting — you can use it inside the loop. Watch a kangaroo take bigger and bigger hops as i grows.

A fox reaches a river. If it has enough energy it leaps across; if not, it stops for a rest. Code can choose between two paths using if and else.

Mission control counts down from 5 to 1, then launches. A while loop keeps repeating for as long as something stays true.

Two racers, and even you don't know who wins. Math.random() gives a surprise number every time you press Run.

A bird climbs an invisible staircase: a bit forward, a bit up, again and again. Two commands inside one loop make a zig-zag pattern.

A car drives through the paint shop again and again. On even trips it comes out red, on odd trips blue. The trick is the remainder operator %.

A car obeys a traffic light. Red means stop, yellow means get ready, green means go. Three possible answers means you need else if.

A tree breathes: it grows, grows, then shrinks back. Loops don't just move things — they can change size, colour, and anything else.
