There are 25 bright LEDs on the micro:bit screen. Let's use them to create some cool animations!

Happy unhappy face
Draw an unhappy face instead of the blank screen. Click on the dots
in the second show leds block until it matches the blocks below.
Now you have an animation (cartoon) that shows a happy face,
then an unhappy one, then a happy one again, forever (or until
you turn off your micro:bit)!

basic.showLeds(`

Your turn!
Pile up more show leds blocks to create an animation! Create an
animation with at least 5 pictures. What does this animation show?
