The Sandstone Shredder can do little more than shred things with its claws. It can barely move, and has low intelligence.
About this creation
The Shredder has a weak shell, but its defense is not important. It's only purpose is to shred humans and vehicles close by.
The Shredder's small eye shows its lack of good sight and intelligence.
Sandstone Raptors and other flying creatures hold it in their talons, and drop it down on human soldiers and vehicles. It shreds whatever it can reach, but is usually destroyed quickly by anyone who has gotten out of the way. The Shredder is the Sandstone version of a grenade.
My second Sandstone creature is so small because I didn't want to destroy my Raptor yet, but I wanted another creature. It's not very impressive, but it works. Sort of.
