WAVE DASH: While spinjumping, hold run and double tap left or right to become temporarily invulerable and dash through enemies.

HAMMERBALL: While in the morph ball, hold down and press 'Aim down' midair to preform an incredibly fast downward attack. Destroys speedbooster blocks and utilizes the shinespark contact damage index

GAUSS MISSLES: A direct upgrade to your standard missiles. Greatly increases their travel speed and preforms 1.5X more damage.

To place these item PLMS using smile, you'll need to add the included .gif files into smile RF's "PLM" directory.

DISCLAIMER:THE NEW ITEMS DO NOT HAVE CUSTOM MESSAGE BOXES! Adding the new message boxes for these items is up to you, and can be done with existing resources somewhat easily.
