How do we get out of kraid after we defeat the boss.?

Go to the far left with the Chozo statue and you get the speed thingy.

Go then jump down to the left and start running so you can blow up the rocks, but don't stop or you have to do it again!!

Um, well, I can only presently remember how to get out of Kraid's room. You need to go to the far left of the room and blow up any rocks you find. Keep going to the right until you find a Chozo with a Speed Boost Node. Pick it up, then get a long running start, where eventually Samus will break the sound barrier and zoom off, blowing up certain walls and enemies while you go. Just don't stop running until you hit a wall you can't plow through.

When you beat him go to the room to the far left. You will get the speed booster. The n go to the edge of the room and start running, you will activate the speed boster. Keep running THIS IS VERY IMPORTANT before you reach the very end,there will be a door, you can't run through the door you'll have to shoot it before you hit it. Once you gat to the next room, shoot the blocks and cimb up the room, ignore the first door to the left, unless you want a missle tank. Keep climbing up and go through the second door to the left. Use the ceiling lift and go to the end and exit the room. You will have to shoot the blocks in the nextroom on the floor. You'll drop, then go to the door on the left again, use the morph ball boost and exit the room keep going until your back in the main section. There you go!( What do you mean " we")
