There are four pieces of armor in the second attack. The Head: Unlimited Remote Control, The Body: Easier Recovery, The Arms: Unlimited Bomb Throw, The Legs: Unlimited Kick Bombs.
To get the Guardian armor you have to get certain bombs and in the right place.
The Head: to get the head, go to the nature planet and go to the door with the steel door with the swirl on it. Throw a shadow bomb at it and cross the lava with an ice bomb.
The Body: to get the body, go to the wind stage, to the place with the four statues, go up the stairs, throw an electric bomb in the air and blow the pillar up, place a wind bomb and blast yourself to the other end.
The Arms: Water stage, to the right, metal pillar, earth bomb.
The Legs: In the casino stage beat Zhaona and go to the hall with the two card blugers and go threw the place were the bunny was.
(P.S. the parts are in electric force fields, blow up with electric bombs.)
