Mario & Luigi: Bowser's Inside Story (DS) - Cholesteroad - Magic Window

After learning the special attack Magic Window, you can take on another challenge at the Cholesteroad section of Challenge Node. For this challenge, after a brother warps and emerges from a window, press the button with good timing to score a point. If both brothers are connected while emerging from the same window, you have to press both buttons simultaneously. As the streak progresses, windows with brothers appearing will steadily go faster. Score 120 points to achieve the A Rank and you’ll receive the Siphon Gloves.
