Using static Regex functions that take in a pattern is bad because the pattern constantly needs to be re-parsed. With https://github.com/space-wizards/RobustToolbox/pull/5107, the engine has an analyzer to warn for this practice now.
This commit brings most of content up to snuff already, though some of the tricker code I left for somebody else.
* Fix capitalization for pirates and rats
* Deal with replacements better
* Be smarter about caps
* Do last word properly
* Variables named a bit better
* Fix Consistency
* Undo change that's not needed anymore
* Fix up pirate since it doesn't need to check early either
* Make mobster replacin' a bit better anyway
* Remove extra space
* Use capture groups for mobster in', add comments for first and last words
* Slightly more clarification with comments
