very possible, and theres even a variety of ways to do it, you can use springs (which kinda freaks out)
or you can make a closed loop of hinged objects and add force in the opposite direction than that of " the object to the average of all the 'loops' objects." (quotations because its kinda confusing)
for a bouncy ball type blob this method works really well, and if you don't crush it beyond its center (which shouldn't be happening anyways) like with spring objects, it can crimp or invert.
for meat cube type of things, springs are really the way to go.
