Ice Beam Before Flaahgra (IBBF) is a trick in Metroid Prime that allows for the Ice Beam to be acquired immediately after getting the Morph Ball Bombs in most speedrun routes. It is a lengthy wallcrawl that traverses a lot of rooms, but it avoids having to do the puzzle in Energy Core and skips needing to have Wave Beam to go to the far region of Chozo. Depending on the route, it can also be counterintuitively referred to as IBBFAF (Ice Beam Before Flaahgra After Flaahgra), as some routes incorporate this wallcrawl after defeating Flaahgra.

Once you have transitioned into this room, you can choose one of three paths depending on your preference: Left side, right side, or bottom.

Left Side
Wallcrawling using the left side of the room is the fastest way of traversing this room out of bounds, and is the most common method for top-level speedruns. However, it is also the most complex and difficult of the three methods, and the most prone to failure if you don't have the proper experience.
