If you're going to be the only person on in your Tribe and Milk runs will be difficult, you can use the Obelisk to store the milk instead of a fridge. The spoil time will not move, and you will guarantee yourself some breathing room while raising the babies!
I got a level 150 lightning egg and I was so excited to hatch the egg...that when I went to put the egg down I accidentally ate it instead. :( ps4 users: R2 ISN'T GONNA DROP THE EGG YOU'RE GONNA EAT IT LIKE ANY OTHER EGG. REMEMBER THIS. LOGIC BEFORE EXCITMENT.
