Step 08 — Make the crab chase the character

Now we're going to make the crab chase the child. Select the crab sprite in the bottom-right corner and select the commands shown above from the Control and Motion menus. Note that the Forever command wraps around the actions to create a loop, meaning the crab will keep chasing the boy until you press the red stop button. We've changed the move steps from 10 to 2 to slow the crab down. Click the green flag to go.
