Tattoo happens to have two henchman who are invincible. Ignore them and focus all of your attention on Tattoo. Immediately start off with a punch combo and then run to the other side of the room. Once on the other side of the room, reposition the camera (by pressing Black button twice) and watch for Tattoo. If you can get him alone, take him on with a punch or kick combo. He is more susceptible to throws than Sickle. Once he is down, retreat to the other side of the room and repeat the process. There are two full Healths in the opposite corners of the room where the laundry baskets are. Make sure you have enough time to get in and out of there without getting trapped. Use the Dive if you have to get by Tattoo or the henchman. This is an extremely difficult boss battle due to the two invincible henchman. Just remember to be patient and wait for the perfect opportunity to attack Tattoo.
