Recently my daughter brought her male veiled "Spin Doctor" over and we "introduced" Ichabob to him. Needless to say the colors were magnificent! Watching them swell up, flatten and hiss was a treat! My daughter noticed that the fleshy sides of their casques were slowly moving forward and back and forth. Has anyone else seen this? Well, after about a minute Ichabob lost his colors and backed down. Now my daughter is boasting that her cham can whip my cham! Lol! BTW, we were very careful with them and the meeting only lasted a few minutes.
