this is dirk if he was an undertale character As i remember, the normal enemies will have 2 attacks The first one is a single dot that follows the heart and gets longer while moving, just to be annoying. The second attack is raining dots (they warn you where the dots will land), seems simple enough, easy fight, but when the two attacks mix (i remember some fights do that) its annoying. Anyways dirk would be found at that mushroom area.
