Mouse level 50 and 55

I cant find the mouse on these levels any help?

on level 50 he comes up virtually behind the fridge so that you can only see half of him just by the handle.

on level 55 he comes up by the table that holds the thread and pattern for the mat right by the cleaners head.

Thanks I have now found them with no problem cant understand why I didnt see them over the last 3 or 4 goes.
