Using the Counter

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.

1. 1Add the kangaroo

   Create a kangaroo.

   createAnimal("kangaroo")

2. 2Growing hops

   Loop 5 times and move i * 20 steps each time.

3. 3Count out loud

   Add a say line inside the loop that shows the hop number.
