How to unlock the Sphinx' Riddle achievement in Batman Arkham City - Definitive Guide
You can easily make the 8 jumps here if you look at the gargoyles and press RB when one is highlighted.
Note: You'll likely want to clear the two-face thugs out before you start this.
Here is the videos of all her riddler grid items if you do not have all of them unlocked from interrogating thugs as Batman.
All the videos are from Batman Arkham Videos youtube channel, I take no credit for this.
Yes, Catwoman has Riddler trophies too. They are much easier than Batman's to collect though and they do show up on the map as ? after Batman interrogates an informant. For some of them, Batman will have to open the area up for her, but the majority are easy to get to. Batman can't pick up the pink Riddler trophies. You have to play as Catwoman to get them.
They were all pretty easy to find and didn't take too long to find. You can follow this video for a walkthrough (thank you to Caofontaine for the video).
Much like collecting the green icons as Batman, the red ones found throughout Arkham City are to be collected with Catwoman (and in fact can't be collected as Batman). These are all much more straightforward than Batman's since she does not have any gadgets. While playing the story, keep interrogating the glowing green enemies, doing so will show the locations of these on the map.
