The Burrowing Jaw is large indeed at around the size of a Capybara this Jutter Jaw is larger than all of the other Squid Rodents that it shares the burrows with and it uses its power to its full advantage.
With how much larger the Burrowing Jaw is than other Squid Rodents usually no bigger than a marmot the Burrowing Jaw can easily overpower other borrowers from their homes simply by being so much bigger. The only animal that even comes close in size is the burrowing Blish the Dodirt whose lightweight skeleton inherited from their flying ancestor makes them far lighter and easy to overpower.
Burrowing Jaws make their homes wherever they see fit living in burrows along the sides of hills in the open grasslands and feeding on roots and shoots of grass.
Unlike other Squid Rodents, Burrowing Jaws are not social animals living in burrows by themselves as males have no parental involvement, and females crushing beaks are well-equipped to defend themselves and their young from predators that try and get in burrows as well as subterranean Sneasels stoat like Foxskin descendants whose flexible gladius lets them slink through burrows in pursuit of prey.
The rather invasive habits of the Burrowing Jaw combined with their large litter sizes and fast breeding rates have displaced many of the other burrowing animals of the Grasslands. Some like the Sqerboa have returned to the surface with their modified legs in tow.
One, in particular, is the Dodirt burrowing Pigeon Blish that are the only flightless bliss to have forearms long enough to walk on have been pushed out into the open world. To keep themselves safe from the various predators the Dodirt started to move into Lichen Forest stands of connected Absorbent Sucker trees encouraged to grow together by the trampling of Brute Grazers.
And it is amongst these shadowy stands of Lichen Trees you kind find The Forest Wanderer
