From their website, there are currently 4 tube colors(2 more coming out in winter), and each tube color has the possibility of 10 adults. So, if you were to get more than one, while you would probably get a different character with the same color tube, you would be guaranteed a different adult if you got a different color. Also, about how big are they?
What I would like for Tamagotchi is maybe an attachable little tube/pouch thing that worked the same way as the Meeba one does, but after you get your first adult you can take off the tube/pouch and raise more characters without getting a plush, but you could buy extra pouch/tubes to attach and get a random plush. I can't really see how that ever could work, but...
