Personally I'd go down the regex route too for preference. If the find/replace chars that you're using are always the same then you can improve the effeciency with just: 

$string = 'Snakes';
$string =~ s/s$/X/;

If you want to take the substr() route then try: 

substr($string,-1,1,'X');

[download]

That will replace the last character whatever it is with the X. For more details I'd also point you towards the perldocs - if you don't have access to the perldoc function then look it up on http://www.perldoc.com.
