She's with Cthulu, recovering from fatal injury. However, she receives another dose of Amnesia and can't seem to remember Quote. Beat Mapignon, come back, shove that mushroom forcefully in her mouth, memory recovered. Leave the plantation, come back, she isn't there? After her recovery, she must have gone to find you...
After doing so, because you were in first cave fighting off blood monsters, she decided to go look at the statues. After starting a conversation with tree guy (I don't even...) you fought the core. As the island was shaking, and Curly was about to leave, Heavy press smashed into her pure metal, and fallen. With her remaining energy left, she crawled over to the right and made a ruckus. Brutes lifted her away, but her weight kept them from pushing her into the door. (Too many brutes lifting her at once. Curly wasn't considered a threat anymore, and they left her.
(After heavy press sent her down, blocks covered his way out. This could happen because of the block flood, and the fact that iron mass smashing into ground sends waves of soundup into the sky... right?)
