Coramon

Coral reef mon, somewhat large and slow moving but very sturdy, circumferentially mostly evenly distributed in its ability to sense, attack, and move, and able to fire water jets (which don't do much non-elemental damage but do carry elemental damage) from numerous points as a ranged attack so long as its internal water tank isn't empty; it can also spin in place fairly rapidly and has numerous sharp projections on its surface; if flipped off its feet, it becomes less able to move and much more vulnerable, but it can then attack with its legs, and its shape allows self-righting

Upgrade to Coramon adds greater reach.
