Your regexps are matching anything that starts with 'y' or 'n' (any case). Just expand and anchor the matches to look like this: 

if (/^y|yes|n|no$/i)
    {
        if (/^no?$/i) 
            { 
                print "Begone, evil peon!\n"
            } 
        if (/^y(es)?$/i)
            {
                print "YIPPEEE.!!!!\n";
            }
    } else {
        # Validate user input and return message if invalid
    print "\n\n=====================================\n";
        print "You Have Entered and Incorrect Option\n";
        print "Valid Options are [Y/N]\n";
        print "=====================================\n\n";
        &answer;
    }
