You have to It's better if you dereference the ref outside the quotes :) and ofcourse do it properly
print "The value of \$fer is ",%{$fer},"\n";
print "The value for the key \"mickey\" is ",${$fer}{'mickey'},"\n";

    Nitpicky time: one of the reasons for Perl's line-noise rep is lines like:

    print "The value for the key \"mickey\" is ",${$fer}{'mickey'},"\n";

    Using qq instead of the double-quotes and the arrow as the dereferencing operator, you'd get (IMO) a much cleaner: 
    print qq(The value for the key "mickey" is $fer->{mickey}\n);

      Actually, the escaped double quotes were there in the root node. Since the question was about references, I didn't bother to edit THAT part :)
