@MetalShavings - Sorry, I was out of town this weekend. I took a quick crack at Sprut for your fish part - since it seemed the most interesting to me.
1/4" TiCN 3-flute carbide endmill @ 5100RPM / 68 IPM with a 10% stepover (per HSMAdvisor), full 1/4" depth of cut. I left 0.005" radial stock for a 1/8" endmill to clean up for a nice surface finish. I also added spotting and drilling to get an accurate time estimate. 12:56 is Sprut's time estimate and the stepover of 10% could probably be pushed to 15% (maybe even higher) to shave more once things are well tested.
Let me know if you need some prototypes ;-) Files should be attached to this reply.
Disclaimer: This is how I would machine it. As always, YMMV.
