Dev Update: Encounters: Check! (Patreon)

Above: These friendly crabs are roaming peacefully, then some adventurer gets a little too close... and the crabs are like... "oh hell no, son".  They begin to chase the dude.  He in his false sense of courage decide to get the attention of all the crabs he sees.  Then in a moment of wisdom decides maybe he pulled too many and books it.  Coward.  The crabs lose interest in him as he gets far enough away from their homes, and they return.

Combat is next.
