 ### Instructions
-Add a series of `move [] steps`, `turn left [] degrees`, and `turn right [] degrees` instructions to a sprite in Scratch:
-- Experiment with changing the number of steps you move.
-- What happens if you increase the number of degrees you turn right or left?
-- Can you make the cat go straight up and and then back to where you started?
-- Can you make the cat go straight left or right and then back to where you started?
-- Can draw a square?
