Here's how it works in this phase:

The Dark Star Core is protected by Fawful, who is invincible in this stage. Fawful will retract the required appendages if they are attacked, including the hands. If Fawful retracts the right arm, I take damage, so don't attack it until it's vulnerable!

The Dark Star Core also allows Fawful to levitate for a short time, just long enough to outlast any attack.

Also, in the original battle, Fawful's glasses have to be broken first.
