You don't want to get two song powers for the Galapagos lights?

Also the wolpertinger attack will be two separate tier echoes, either two tier ones or one tier one and one tier two if you want a memory in addition to the item and skill - the attack is a separate cause for an echo (a recurrence one) than the ghost wolpertinger encounter (which is a plot echo).

That said, the last echo works as is and is approved.
