CU-L8R [O]'s Comments

Any color and can look physically different/modded.
You're welcome to take what you like about CU-L8Rs to inspire you to make something that suits your interests more too, if you like rabbits, dogs, or hawks and what have you! I'm not gonna come after anyone for having something similar. 

Sure! I'd personally recommend instead using it as a jumping off point, in case you do decide to make it profitable someday, but yeah, anything that's for fun these are fine for!
