How do i rip sprites off .MHK files?

I am trying to rip sprites from a Mohawk Engine game called Arthur's Birthday, from common knowledge, the sprites may be stored in .MHK files inside the game's data folder. However i cannot find anywhere on the internet how exactly i can open/extract these .MHK files, and the contents within them.
Can someone tell me what program i can use to open these .MHK files? or convert them or something?
