The follow example builds the hash lookup table with a single regular expression with capture, using the @array = $str =~ /(regex)/g idiom. It is a useful technique to master.

use strict;
use warnings;
use Data::Dumper;

my $str = 'Happy Joy 002245:Dubloons 002256:hats 034523:paper clips 23
+2344:pants 233394';

my %capture = $str =~ /(\D*?)\s+(\d+):?/g;

print Dumper(\%capture);

And the output -
$VAR1 = {
          'pants' => '233394',
          'hats' => '034523',
          'Happy Joy' => '002245',
          'Dubloons' => '002256',
          'paper clips' => '232344'
        };
