With only 10,000 health and 200 attack power, this enemy is not very threatening. It is red, so it can easily be dispatched with anti-Red footsoldiers like Axe Cat or Swordsman Cat. It does have a quick attack rate, however.
This enemy appears to be a Pigge caried by three Doges. Pigge appears to be wearing a white headband. Its attack animation is that the three Doges jump up in the air and the Pigge does her normal attack animation slamming into the ground.
