Being born with a shell means you are naturally very stealthy.
The fact that you are also born low to the ground and slow and steady is just icing on the proverbial (tortoise-sized) cake.
But sometimes you find that you want or need to add even an extra layer of stealth.
For instance, maybe there are teensy tiny round particles on the prowl, and you need to be absolutely sure nothing will give away your location to them.
For this, what you need is a shell for your shell.
The pros call this a “super stealth shell.”
Like so.
