Ratkin gene expansion

Outside the territory of the Ratkin Kingdom, there are also many distant relatives with blood similar to the Rat of the Kingdom scattered. The dry season, war, and spiritual energy took them on different paths and ultimately led them to meet under the banner of the kingdom.
This extension includes three heritable mouse species (two more will be added later):
Jumping rats are good at animal husbandry and long-range combat, but they are relatively defeated in close combat. Compared to other mouse tribes, they are smaller and more fragile in size, but more sensitive and less susceptible to attacks. When encountering danger, they can use special jumping to escape.
Moles are skilled in mining and close range combat. Due to the decline in vision caused by their original habitat in mountainous areas, moles can use their digging abilities to quickly drill tunnels and launch surprise attacks on enemies. In unfavorable situations, they can also be used to escape, but enemies may continue to pursue them before the tunnel collapses ......
Flying squirrels excel in spiritual and logistical work (intelligence, craftsmanship, art), but their high-intensity work is extremely slow and they are naturally endowed with unique spiritual abilities, making them suitable for guerrilla warfare. Flying squirrels have a sparse natural population and are commonly found in libraries, research institutes, and other places.
All three species have independent ear tail appearance, child stage adaptation, and a set of standard equipment. From the rifles and robes of the arid guerrilla forces, to the hammers and workwear of the mining rats, to the dress and rose pistol of the flying rat librarian, these equipment will also appear in the world along with the corresponding bloodlines of the rats.
