The emergence of larger, faster, and more social prey posed a challenging puzzle for the omniclongulators. For a long time, most of them went after small terrestrial prey and medium flying prey, but new opportunities on the island urged more specialization. The first proto-esemmgees finally started evolving when the toothadon established itself as a common creature, eventually refining itself to the form we see today.

Like its relatives, the esemmgee has stronger bullets than its ancestor. The “mud” portion has largely been taken out, with the bullets essentially being made of tiny pebbles cemented together with thick keratin. This makes them more heavy than the omniclongulator’s, though not quite the same as Timothy's yet. Strong bullets by themselves aren’t the esemmgee’s most notable adaptation, though. The esemmgee is special due to being able to fire multiple bullets in rapid succession, up to 7 at a time. This almost guarantees that the esemmgee can hit a moving target, and it also allows them to take down multiple prey items at once. In order to store its bullets for the occasion, the esemmgee has a specialized growth of the skull called the “magazine”. This organ has a springy tongue-like organ at its base which it uses to push up the next bullet after the previous one has already been fired. This is a lot more efficient than having to regurgitate one bullet at a time directly from the diverticuli, and is the key to the esemmgee’s rapid fire rate.

To make up for having to shoot 7 bullets at once, its air sac is much stronger as well. It is very massive, and droops from the long neck even when completely deflated. A lattice of cartilage prevents it from exploding due to the highly pressurized air stored inside. An especially strong ligament, known only as the “funny ligament”, runs down the esemmgee’s neck and serves to protect it from recoil. Due to the number of bullets it fires, the esemmgee also has a much larger number of gut diverticuli, to the point where they now hang down in a large clump that resembles a large gut or “beer belly”.

Due to its regular consumption of medium to largeish prey, the esemmgee has a deeper digestive patch surrounded by longer, trunk-like tentacles, which help to grab and dismember prey items into smaller bits. The digestive area itself is coated in a thick mucus and thick skin to help prevent laceration.

Though the esemmgee is quite large even for a clongus, it still has predators, especially at a young age. Its rapidfire deters predators very effectively if it actually knows they’re coming, but being ambushed from behind by guillotine mamals or other clonguses does happen. To mitigate this, the esemmgee’s tail has reduced to a thick bony area on its rear, no longer actually sticking out. The esemmgee is able to briefly balance on its front “foot” in order to deliver a powerful kick using its hind “foot”, potentially breaking the predator’s bones if it gets a good hit with the tailbone. An armored plate on their face shields their large and well developed eyes, can be used to defend from predators, and settles fights between adult male esemmgees should they encounter each other.

The esemmgee has thick, circular, cartilaginous pads in its “feet” for stability. Older individuals usually hide in more densely forested areas. Esemmgees have a leopard-like pattern to blend in with piss flora, usually crouching down to make themselves less visible amongst the foliage. It also buries its eggs deeper than other clongi do to avoid predation, with its digging ability aided by the cartilaginous foot pads.
