For anyone who wants a decent zoo-building modpack.
There are around 250+ mods present in this pack, some of which do come with a lot of data. Take that into consideration before loading any server with it. (Minimum 8 GBs, most likely.)
The mods mostly focus around adding more mobs, more building blocks, and more game mechanics that makes catching mobs and building a fun zoo around them a little easier. You probably won't run out of animals to build enclosures for here, though. There are some combat mods to make the mob-catching parts a bit more reasonable, since there are a ton of new mobs you'll need to catch and/or defeat.
