Golem and mantis were part of an old build of the game. In the new version they will be replaced. Mummy on the other hand is planned for future levels.
I will not be translating game myself but it can be done by editing csv files in games Streaming Assets folder.
I've plan for making a manwolf like creature for Annie's level. It's just an idea at the moment. I will have to see how it turns out.
