@val = $mapp{"FirstKey"};

[download]
This assigns a reference to @arr to $val[0], because $mapp{FirstKey} contains a reference to the array @arr. When you stringify the reference, you get something like "ARRAY(0x7ffafc013bf8)". If you wanted to make @val a copy of @arr, then you can:
@val = @{$mapp{FirstKey}};
