Easy end game farming of these:

Extinction has the cryoball, cryofridge and Dino leash engrams... learn these.

Make and charge cryoballs.

Make cakes.

Make Dino leash.

Go hunting for the snails.

Tame them then cryo them.

Each cryoball holds one animal β€œfrozen” until thrown back out (like a pokeball).

Continue until all your balls are filled.

Place snails, place Dino leash (they will have a β€œlock” above their heads.

Set them to roam and they stay inside the leash radius.

Feed cakes as normal when hungry. :-)
