Mamaroo!!

So I got a mamaroo from a lady off a facebook selling site and it didn't have the mobile thing so I went on the website and looked at them and I don't know what year it is. Im just wondering if any of you mommas have the same one and kjow what year it is because it doesn't look like the 2014 or 2015 on the website. I asked the lady and she got it from a friend for a foster baby so she didn't know. Thanks! He loves it but he loves his mobile on his bouncer so I'd really like to get one for this.
