early power bomb: transit station
Screw attack to the high ledge, getting some ghetto effect from the wall when you jump off.
The next part can be tricky. Line yourself up with the tunnel and jump off as soon as the ground below you is no longer visible. Use your second jump just before the peak, enter screw attack mode again just before the peak, then quickly screw attack once. The four taps of B should all be about a half second apart when done right.
Once you have the expansion, use a 3bj-bs jump to get back inside the tunnel.
- A 2bj-bs jump also gets the height if done well enough.
- You must still collect the power bomb itself at some point to finish the game. Otherwise, the ing flying cache in Dark Oasis will never appear, preventing you from getting the Sky Temple key.
