Dear Masters,
Given this hash I want to identify animal that:
1.Occur more than once within the states, AND
2.Occur in more than one states.
In this case the animal is HIPPO. 
my %bighash = (

 'Arizona'=> {
              'ZOO_1' => [ '5','HIPPO', ['some arr'],['some arr']],
              'ZOO_2' => [ '10','HIPPO',['some arr'],['some arr']],
              'ZOO_3' => [ '2', 'PUMA', ['some arr'],['some arr']], 
              'ZOO_5' => [ '1', 'PUMA', ['some arr'],['some arr']], 
            },
'Indiana' => {
             'ZOO_9' => [ '25', 'ZEBRA', ['some arr'],['some arr']],
             'ZOO_5' => [ '13', 'MONKEY',['some arr'],['some arr']],
             'ZOO_6' => [ '23', 'ZEBRA', ['some arr'],['some arr']],
             },
'Nevada' => {
             'ZOO_3' => [ '3', 'HIPPO', ['some arr'],['some arr']],
             'ZOO_7' => [ '11', 'HIPPO',['some arr'],['some arr']],
             'ZOO_4' => [ '21', 'LION', ['some arr'],['some arr']],
             'ZOO_12' => [ '13', 'MONKEY',['some arr'],['some arr']],
         },
      );

Such that in the end it simply have: 
Arizona
ZOO: ZOO_1 ANIMAL: HIPPO
ZOO: ZOO_2 ANIMAL: HIPPO

NEVADA
ZOO: ZOO_3 ANIMAL: HIPPO
ZOO: ZOO_7 ANIMAL: HIPPO

What's wrong with my code below such that it doesn't gives the answers correctly? 
print Dumper \%bighash ;

foreach  my $states ( sort keys %bighash  )
{
    print "$states\n";

    foreach  my $zoo ( keys %{$bighash{$states}}  )
    {
        my $cur = $bighash{$states}{$zoo}->[1];
        my $count = 0;

        foreach  my $nzoo ( keys %{$bighash{$states}}  )
        {
          my $nxt = $bighash{$states}{$nzoo}->[1];

          if ( $cur eq $nxt )
          {
            $count++;

            if ( $count > 1  )
            {
                print "ZOO: $zoo ANIMAL: $nxt\n";
            }
          }
            
        }               # -----  end foreach  -----
      
    }               # -----  end foreach  -----
}               # -----  end foreach  -----
