search and replace characters in one string

I have lines like:

Dog Cat House Mouse
Dog Cat House Mouse
Dog Cat House Mouse
Dog Cat House Mouse

I'd like to replace characters only in $3.

H -> Z
s -> W
e -> x

Resulting in something like (where $1, $2, and $4 are not changed):

Dog Cat ZouWx Mouse
Dog Cat ZouWx Mouse
Dog Cat ZouWx Mouse
Dog Cat ZouWx Mouse

I'd guess SED might be best but I'm really new. Sorry to to include any sample code.

Mouse::Util(3pm)					User Contributed Perl Documentation					  Mouse::Util(3pm)

NAME
Mouse::Util - Utilities for working with Mouse classes VERSION
This document describes Mouse version 0.99 SYNOPSIS
use Mouse::Util; # turns on strict and warnings DESCRIPTION
This module provides a set of utility functions. Many of these functions are intended for use in Mouse itself or MouseX modules, but some of them may be useful for use in your own code. IMPLEMENTATIONS FOR
Moose::Util functions The following functions are exportable. "find_meta($class_or_obj)" The same as "Mouse::Util::class_of()". "does_role($class_or_obj, $role_or_obj)" "resolve_metaclass_alias($category, $name, %options)" "apply_all_roles($applicant, @roles)" "english_listi(@items)" Class::MOP functions The following functions are not exportable. "Mouse::Util::is_class_loaded($classname) -> Bool" Returns whether $classname is actually loaded or not. It uses a heuristic which involves checking for the existence of $VERSION, @ISA, and any locally-defined method. "Mouse::Util::load_class($classname) -> ClassName" This will load a given $classname (or die if it is not loadable). This function can be used in place of tricks like "eval "use $module ()"" or using "require". "Mouse::Util::class_of($classname_or_object) -> MetaClass" "Mouse::Util::get_metaclass_by_name($classname) -> MetaClass" "Mouse::Util::get_all_metaclass_instances() -> (MetaClasses)" "Mouse::Util::get_all_metaclass_names() -> (ClassNames)" mro (or MRO::Compat) "get_linear_isa" Sub::Identify "get_code_info" Mouse specific utilities "not_supported" "get_code_package" "get_code_ref" SEE ALSO
