ITEM CHECKLIST:

Kitchen Note (ALL)Approach the carousel and ride it, then joke around (until you're all out of jokes) with the No Pun Intended book Riley gave you. Check out the 'Fast Burger Pickup' kitchen on the side to find a [KITCHEN NOTE] inside. Be sure to check out the sharesnap behind the escalators as well. The whole facebook advertising is pretty upsetting (and as if that's going to be the only large social media company ever - fortunately a naive thought), but other than that, the scene is well thought of.
Head up the escalators on the other side of the hall and enter the arcade. *Before* you play the game Riley is standing next to, first check out the other 'playable' arcade race game in the corner (another reference to ND's Jak). If you inspect this you'll automatically gain the [NOBODY'S PERFECT] trophy.
Now play the fighting game. It's not hard to win as long as you remember that the + sign indicates that you're supposed to press the grouped buttons together. You have a time bar for each combo and the game's fairly generous. You'll want to give it your best and try not to get hit even once (get all combo's correct in one go). If you manage to never get hit you'll receive the [ANGEL KNIVES] trophy. After this a scene plays.
Move through the hall and enter the hall with mannequins. You can push the one standing in the light, then move through the exit doors. After the scene you'll have to soak Riley wet. Tap the R1 button and quickly aim and shoot at her with your water gun. After this you'll play hide and seek, where the first one who hits the other person with a burst of water wins. If you win twice you'll get the [SKILLZ] bronze trophy. More scenes will play...
