"Pinky the Ninja Mosasaurus", made an image based on a character my three-year-old daughter came up with.

Originally she was holding the ninja sword with her flipper, but my daughter said "No that's not right" and explained that obviously the sword should be protruding from the ninja-mosasaurus' back. Also initially asked me to make her blue. Then had me change to red. Then purple. But now, finally, the image is perfect.

Following the whims of a three-year-old's OC design has been fun!
