Dimensional shamblers, as the name suggests, are capable of travel through multiple dimensions. "Shuffling toward him in the darkness was the gigantic, blasphemous form of a black thing not wholly ape and not wholly insect. Its hide hung loosely upon its frame, and its rugose, dead-eyed rudiment of a head swayed drunkenly from side to side. Its fore paws were extended, with talons spread wide, and its whole body was taut with murderous malignity despite its utter lack of facial expression."
-H.P. Lovecraft & Hazel Heald, The Horror In the Museum
These are, undoubtedly, the best depictions of Lovecraft creatures that I've seen on this entire website. I am genuinely looking forward to seeing more of these from you.
Um, I think the snippet of Lovecraft you quoted was actually referring to Rhan-Tegoth (or more specifically, the proprietor of the wax museum dressed up as Rhan-Tegoth), not a Shambler.
It is the closest description we have of what a dimensional shambler could look like, since he was purportedly wearing the hide of one, so I'm going with it anyway.
