For the Twentieth Challenge, it is all about facing 10 Inkies in an alleyway. Your compass can find that.

The Twenty-first Challenge is very simple as you must paint a block orange. Go ahead and do that. Be sure to get all the Eighth Raydian Batch for a grand total of about 82.

I believe that all the challenges are done for this area. By this time, you should be at the gate that you originally went through. Time to start painting some areas and freeing some Raydians. I’ll try and guide you as best as I can.

Start with the one alley with the pool surrounded by four trees. Go paint this area completely and you will have the Ninth Raydian Batch and the Tenth Raydian Batch for a total of 98. You should be able to find the Sixth Style here.

Go ahead and leave the alley to the exit to the left. You will see the building block that you had to paint red during the Eleventh Challenge. Paint it completely, and get the Eleventh Raydian Batch for a total of 106.

Across from that building block is one that had one of the Landmarks. The other side of this building block is the courtyard. Paint it up and free the Twelfth Raydian Batch inside for a total of 114.

While you are painting that long building block with the landmarks on it, use the Z pad on it, twice. You will find yourself on the roof, and you can concentrate on painting all the places that you cannot get to from on the street. Paint these areas (and the one around the corner where you found a billboard) and you will find the Thirteenth Raydian Batch and Fourteenth Raydian Batch for a total of 130.

Go to the one area where you had to face the Sixteenth Challenge to paint a section purple and yellow. Paint all this area, including the small little “houses” here. You will receive the Fifteenth Raydian Batch for a total of 138.

Keep going until you get to the corner here. You might notice that there is one white section that you cannot reach, and yes, you will need to get it. I will tell you how, but go ahead and collect the Sixteenth Raydian Batch for a total of 146.

From there, just go down the street corner and paint all that you see there. Collect the Seventeenth Raydian Batch for a Total of 154.
