So I was playing S3 with some people at a Smash Fest today, and I was on Gepetto's Workshop when I noticed something. Normally, when Robin Hood uses his wall attack arrows, he faces away from the wall while shooting them, and then leaps away perpendicular to the wall. However, the wall on the front right side of Gepetto's is special in that Robin Hood turns to face toward the opponent to perform his wall attack. The significance of this is twofold. First, Robin Hood can actually wall attack opponents next to the wall that he is on, rather than the homing mechanism not working and the attack whiffing in certain situations. Second, Robin Hood can be made to jump away parallel to the wall instead of perpendicular to it after the attack, allowing him to wall attack again. And again. And again. All the wall across the wall until he ends up above the opponent.
