How can I talk to Wynnona (the butterfly)?

Hint 1 of 5:

You need to get up to the mantle where her cage is.

Hint 2 of 5:

The idea is basically the same as what you did to get to the pot on the
mantle in the queen's chambers.

Hint 3 of 5:

You need Fulbert to help you shake one chandelier while you ride on the
other.

Hint 4 of 5:

To do that, you need Fulbert to be able to climb Rock Steady's spear.

Hint 5 of 5:

Another vegetable of sorts will help you here.
