Security Cubes

• Due to a glitch, if the Navi ghost was beaten and then the same Navi version was beaten in the story, the Cube will not open. This is resolved by beating the Navi ghost again.

Bass GS

This requires using the BugFrag Trader in Secret 3 until a total of 300 BugFrags are put in the machine. Once you jack out and jack back in to the square with the BugFrag Trader (and Serenade has already been beaten), a cutscene will trigger that begins a fight with BassGS.

Minigames

CyberSimon Says

Across multiple Cyber Squares, there is a Normal Navi that you can challenge for CyberSimon Says. Enter the correct number of buttons within 1 minute. If you succeed, you will be rewarded.

Location	Correct Buttons	Prize
Yoka Square	60	1 BugFrags
Beach Square	90	5 BugFrags
Under Square	99	30 BugFrags

Double-Up

Across multiple comps, there is a Normal Navi that you can challenge for a gambling game. Pick the right pad and you win, multiple wins in a row will net grander prizes. The NPC won't play anymore once you clean them out. However, if you quit before the final round, you can continue grabbing the lower tier Zenny rewards.
