The forced transformation from human to fish was jarring enough for the woman, the second transformation back to human form was dizzying to say the least. The blonde woman was glad that she had managed to swim out of the cell while she was just a fish. After shaking her head to clear away the sensation, she looked to the side to see a giant squid and two hunks of metal armor, one lying on the ground as a pile, and the other standing/swimming. 

She quickly studied her surroundings. The walls were too smooth, there was nothing she could use to their advantage. She wanted to swim up and help free the mermaid who was stuck in the giant squid's grasp, but she could tell that the mermaid was raging and could probably get out on her own. So, it looks like the best she could do was help get rid of the last swimming automaton. She swam up to take position near Jill, in hopes of being able to protect her in case any attacks came her way. 

Once she took position, she took the rock in her hand, and then looked at the automaton. She shouted "Hey! PEA-BRAIN!" before she threw the rock at the armor. From the sound of the rock colliding with the armor, it sounded like she at least dented it. She then grasped the staff with both hands and prepared herself to fight.
