Hi Jim,
It does. If you look at the bottom of the Swim Fry page it shows related items, it's the Go-Go Grub Tail Mold (not the most obvious name, but that's what it is).
With that said, and to keep you from loosing your mind, I would start with the mold and just cut the tails off and see if you like doing it that way. It's not super hard to get them back in, but it can get a little frustrating. If you are only making them for yourself and a few buddies it's probably not bad. If you are making them to resell I would do a laminate vs. a different colored tail.
Thanks,
Jason
