Down+O(electric pad,) neutral square, square(b*smack uppercut,) up+Square(claw grab,) forward+triangle(jetpack,) neutral O(cake.)
This combo used to give 125 points. 100 points + 25 for the AP burst. Because the cake was reduced by five it only gives 95 points.
Sackboy needed the nerf as he was way overpowered, but increase the claw grab by five points so Sackboy can still get his AP burst. It's not worth even going for the combo now if you're not going to get the extra 30 points out of it.
