[Major Cache Transfer Island obtained]

Growing Isle comprehended that Cache Island was a trap for her and the cause was the old man.

So, when she recovered and Elias was in a coma she expended her strength and attacked Cache Transfer Farm and swallowed the only Major Island which served as the mother of other Cache Transfer islands.

Old Man Card tried to stop her but somehow she made him land on Forbidden island and bind him to the Chest of Damnation. 

She did that for two reasons, to prove her worthiness to Elias Gobarau, her Islander, and also to obtain a Major Island that will serve as a warning to the old man.

But the thinking and reasoning ability was derived using Pentagon and Elias' brains. 

After merging the Major island she knew it wasn't complete, some was missing. A key! Getting the key from the old man, only then the Aspect of Major Island be unlocked.
