Another tortoise swarm.

 Went a bit nuts on the gore.  

The most foul, cruel, and bad tempered Testudinidae

  “Listen, those terrapin got a viscous streak a mile wide, they're killers.  Just look at the bones!"

I was testing out my 3d printer by printing the same file at different scales.  I had to decide what I was going to do with all those tortoise that I printed. 

I figured a tortoise swarm would be frightening.
