To get the ''Grand Grenade set'', head to the Flutter, (Only if it's fixed,) go to Gramps room and look between the wall and the bookcace.
There should be a trunk. Look inside it and there will be the grand grenade set! Give it to Roll and she will give you the grand grenade witch can destroy the cracked wall in the Sub Gate in the lake.
To defeat Mega Man Juno, I found it out after about 500 tries!!!!!!!!!!! Get the Spring Jump Shoes, buster gun with good range, raped, and attack. NOTHING ELSE!!!!
(I'm Not crazy,) Just run around the edge of the battle areana Firing and jumping when he/she/it attacks, and blow its head off 2 times. P.S. Their is NO time limit!
