That likely means you're either playing on a Guest account that's not yet linked to LINE, or you're playing on child's account and you set your age to under 13 when you started the get for the first time.

If you are linked to LINE, then you have to add friends via the LINE app. But to get Alien, you have to invite friends who have not yet played Tsum Tsum. There are lists floating around with dummy LINE accounts you can temporarily add so that you can invite your 30 "friends" and obtain Alien.
