your a alien and you wanted to explore earth but you had a problem.. your eggs that you had that you were trying so hard to keep alive couldn't be without you. So you did as any good alien mother would do. You put them in your bag that was regular shaped with lots of padding so they wouldn't get crushed or anything and started to explore earth while you had your babys with you!

Your ship landed in a backyard of a humans so you went to go look at the house
