[Theory] Kaguya has a second form

[Senju Bean]

She is just another manifestation of the Juubi.

The Juubi has two forms. Fat beast Juubi and the Second Stage Juubi

The Shinju has two forms: the one in the war(stem and flower), the different looking one in the flashback(giant tree with leaves etc)

Hence, Kaguya should sport the same pattern.
