Combine 2 content types into view
Well if I am getting you right, for this issue you should do this; 
Create a new view, and in filters option select type "toys" and again select type "areas", this will give you 2 content types into one view.

For exposed filters, in the filter criteria, select both the fields, "series_taxonomy" and "area_name" and select them as exposed filter.

Hope this helps.
