Putting this in Shipwrecked because I don't see them in normal RoG games so I guess it must be the SW crossover elements.
Started a new RoG game as Warly. Didn't touch the world customisation options.
First, Grass growing in the ocean:
Second, I tracked down a Koalaphant shortly after starting (Tracking time seemed pretty long, ten or so dirt piles) and when I met the creature it didn't try to run away from Warly. Are Koalaphants programmed to respond to certain creatures in their proximity? (Rabbits are still scared of Warly.)
Start a RoG game as Warly. Go bother an Koalaphant.
