How do I access Mystery Mouse on AlphaBetty Saga?

My partner and I started playing at the same time, and have similar scores. But he has a Library with Mystery Mouse and a Royal Guard, while I have none of these things. We cannot work out why. Can anyone help. Thanks.

I have it and my friend doesn't so I guess its the same as the booster wheel in Candy and the club in Farm. Some players will have it and some won't

It could be he has completed more levels than you and it will show up after you complete more levels.

A new clue.  I just got Mummy Mouse (the third library entry).  What unlocks it is getting a certain number of stars at the part you're on.  I got Mummy Mouse with 40 out of 90 possible stars.  So if you've passed some levels with only one star, try them again to build up more stars and I bet you'll get the Mystery Mouse and Royal Guard too.  Each of those relies on a total of 150 possible stars.  Sorry, I don't recall how many stars it took to get each of them.

It is random, some people get it some don't....It is the same with every King game, some people get advantages when there are new things in the games - others don't.

The booster wheel in Candy Crush is after you pass a certain level, I think level 50... but can't remember for sure. The club in Farm Heroes is accessed once you pass those levels shaped like a cow. You need to get three stars to benefit from all three animal bonuses. But if you only pass with one or two stars you are limited to the first and/or second animal bonus on future levels.

I'm not sure if this is true. My friend first got access to the library after level 17, and I've had 3 stars for the first 20 levels and still don't have it. So I'm trying to get 3 stars on all levels and see what happens...
