Return to Samus' ship, then run over to the left corner of the open
area. Run back towards your ship to activate the Speed Booster, then
crouch and quickly walk over to the mound on the left side of the ship.
Face right, angle up (R) and then jump, you'll Shinespark up to the top right corner
of the area where a door awaits. Blow the door open with a Power Bomb then travel to the end of the corridor beyond to find this Power Bomb.
Head to the huge orange shaft containing all the Ripper flying
around, then ascend to the very top and go through the door there. Travel through the following thorn-infested corridor taking care to avoid the thorn traps. Once you reach the next shaft leading up, shoot open the floor at the base to reveal a hidden
passage below. Descend to the very bottom of the shaft, head through
the door you find and go to the end of the corridor to find this Power Bomb
(don't forget to bomb open the wall behind it for a missile too).
From the previous Power Bomb's room, go back to the large shaft and
climb up to the top. You'll find an elevator there leading back up to
Crateria, instead go through the first door on the left wall below it. In the
next corridor you'll find a number of huge Sidehoppers, quickly finish them
off to unlock the exit. Travel over to the far left of the
corridor and use a Power Bomb to blow open the long platform you're
standing on. Once it's clear, fall down into the orange/brown spike
trap near the wall and you'll fall straight through it into a hidden
pit containing this Power Bomb.
From the massive purple shaft containing all the snowflakes falling in
the background (near Spore Spawn's room), go to the very bottom and
head through the door on the right. In the next green corridor, use
the Hi-Jump Boots or the Space Jump to reach the upper cliff straight
ahead. Go through the door to find a load of huge Sidehoppers. Clear them all then travel to the right wall and bomb your way through the base of the wall to
find this Power Bomb beyond.
From the main elevator in the huge green thorny shaft, go to the very
bottom and blow open the floor with a Power Bomb. Descend to the
bottom of the hidden shaft and head through the door there. Once you
reach the small room with the hidden hole, jump over to secure an Energy
Tank and a Super Missile. Once you're ready drop down into the hole and
travel right. Keep going through the spiked-lined corridor to find a tall and very narrow shaft leading skyward.
Here you'll discover another of
the game's many secrets - at the base of the tall shaft
three Etecoons wait patiently for you. They'll then begin to use the
wall-jump trick to climb the shaft, so simply follow them up (with plenty of practice). Once you
reach the apex you should spot a small opening in the right wall. If
you have the Spring Jump use that to get through, or you can jump over
to the wall and quickly activate the Morphing Ball, then hold right to
enter the tunnel (run down to the left side of the corridor and run back to make the jump with the Speed Booster). Go through to find this Power Bomb.
Just after missile no. 4's location past the Grappling Hook blocks in
the huge purple shaft, use a Power Bomb to break open a wall section below
it then go through the left wall to pass through a hidden door. Blast
the huge Sidehoppers in the next chamber, then use a Super Missile to
break through a hidden block in the floor on the left end. Descend
through to find this Power Bomb.
Once you've beaten Crocomire and secured the Grappling Beam, go to the
large room to the left of Crocomire's corridor. Use the Ripper at the
top to swing over to the door in the top left corner of the room, then simply
head through to find this Power Bomb inside the following chamber.
When you enter the large corridor in Ridley's Lair inhabited by
the huge blue and red Sidehopper-type enemies, you should also notice
a lot of large statues around. Go to the far left side of the corridor
and use a Power Bomb to reveal a hidden tunnel at the base of the wall
(you'll also blow open the passage leading down to Ridley's room). Crawl
through to find this Power Bomb.
Go to where you found missile no. 14 in Ridley's Lair, then bomb open
the top corner of the wall behind it to reveal a hidden passage. Use
the Spring Ball to jump up into the hole, then hold A and right,
so that you'll make it through the complicated room without falling
through any crumbling blocks. Once you reach the end, simply descend through the
door in the floor to find this Power Bomb.
In the same underground cavern as missile no. 6 (you reached it by
descending through a sandpit in the huge room with the vertical pipe),
you'll find this Power Bomb on the right side of the area. The Space
Jump and Spring Ball will help you reach it easily.
