CSP Unit 3 Lesson 8.14b
/* Code generated by RoboBlockly v2.5 */
/* Problem Statement: 
    Using your code from Lesson 8.14a, modify the "fillColor"
    code block in the drawFish function so that it uses the
    "color with" code stub instead of the "hex color with" code
    stub. Keep the parameters (red, green, blue) as they are.
    Then change the drawFish function calls in your program so
    that the parameters used are numbers instead of text, with
    values between 0 and 255. (Remember that the number stub is
    found in the Math tab menu.)
    
    See the hint if you get stuck, and don't forget to save
    your work to the cloud in an xml file named
    "YourName_Lesson8.14b"!
