>>49916872Those are two virus. Don't remember the names, but I remember what they do.
The cannon is a basic virus. Just avoid being in the same row that him, and he won't shot you. The cannon is lvl 1, so he will be always open. Lvl 2 and 3 closed the shield in front of them until you are on front as well.
The "tampon" is a cartoony Bronzong. He will jump around in his area, then teleport on top of you, full size, and crush you. If you evade his Stomp attack, he will leave your side damaged. You must then step on it quickly, and break it. That way, it will start to restore itself. Otherwise, he will caught you in a corner, and trust me, that Stomp really hurts.
