Well if you warp zoo and donate to the chest you get a sapling .
Progress:
Most animals have been procured and some cages are being built. Entrance is nearly complete.
EDIT
Animals are now despawning… will try and fix this before opening
EDIT II:
Spawning animals works so I am buying two of each egg then spawning the two animals and destroying the eggs. However I will need sop+ to spawn ocelots, wolfs and harmful mobs
