northern tales 4 secret achievement

In the awards section, I have 87/89. there are 2 secret achievement awards. I can not find how to play. Anything?

You ring the bell 3 times for one and you open the windows for another.
I think one was find all the hamsters, but can't work out the other. Came on here trying to find out what it is.

Hamsters are found throughout the levels under shields, in helmets and in barrels. Just click on items to uncover them.
