What Is This?

[Lateralus_Love]

I didn't feel like posting in the extremely uber old post that I found this in, sooo...I was just wondering, if anyone knows what the ball is in this pic? The second link brings you to the site it's from, but all the captions on those pics just say "Unusual Pastel" o.O

Something like this maybe? Picture is from Baron-Kelly Reptiles site from a visit of his to Bob Clark...
