Leg Upgrade (Mid-Air Dash)

 * Stage: Overdrive Ostrich

This upgrade is at the end of the stage before you enter the door to the rocket. Before you drop down to the door do a skip jump across the gap to a ledge that is blocked. You'll need to use the attack, spin wheel, to destroy the blocks blocking your way, inside is a small room with a capsule. Enter the capsule to gain the Leg Upgrade.

Helmet (RADAR)
Towards the middle of the level, after you slide down the slippery crystal hill with the green crystal block chasing after you, there is a big chasm. What you do is slide down the left wall of the chasm and there will be a path with some stationary enemies. Destroy them and keep going left until you find the capsule with the helmet (RADAR) upgrade. This upgrade allows you to find hidden passages elsewhere in the game when equipt. When useing the RADAR you cannot use your X- buster or any other weapon.
