When you reach the breakable floor where a Squeept insists on diving and smacking its head into the concrete, break the floor open to allow it to jump out. Along the way, you should find yourself back in the large room beyond Norfair's first Save Room. Use your map to make your way back to Brinstar. In the next room, the floor will crumble when you attempt to go right, dropping you to the middle of nowhere. Shoot at the upper right portion of the wall across from you to reveal a Missile Tank when the opportunity presents itself, freeze the Ripper floating around and use it as a platform to Power Grip your way to the explosive reward. Freeze the two Rippers in order to create some makeshift platforms and roll through the narrow passage to reach the other side. Create some more Squeept platforms in order to make your way across the lava and into the hatch ahead. Roll into his arms to reveal that your next stop is Kraid, and continue to the right. Make your way to the right and meet up with another Chozo Statue. Wait for the red bastard to jump out and quickly freeze him with your beam in order to create a nice, chilly platform. In the next room, a Squeept will dive in and out of the lava, obstructing your way to the platform on the other side of it.
