Starry Puffer
Wait for it to deflate before closing distance; its inflated body is immune to weapons.
Best capture method
Net Gun. Catch stars measure quality, not rarity. Bring the target back alive whenever its rules allow it, and reserve Recovery Drone charges for large compatible fish.
Restaurant use
Stellate Puffer Nicogori. Enhance this dish only when its ingredient route is repeatable; a stable Fish Farm supply beats a one-night spike.
