The Astrocetus is a tamable, ridable space whale that must be knocked out by carefully striking the front of its face with a cannon, then fed Extraordinary Kibble. Its platform saddle supports mobile building, passengers, mounted weapons, and bombing, while its warping ability enables rapid travel and repositioning for allies. When encountering one, keep your distance to avoid its bite and powerful tail swipe, using a mobile platform to safely line up taming shots.
