"We'll figure it out when we get back to base!" Nico answered, trying to keep her voice steady so Molly wouldn't freak out more. It was definitely freak out-worthy, but now wasn't the time or place. "Stick close to the sleigh in the meantime, I've got you covered. Help Howard, he might need a second pair of hands!"

In the meantime, she can put the remains of the roller coaster to good use:

"'Coast guard!"

The pile of wood and metal cracked into pieces before resolving itself into half a dozen large golem-like creatures that immediately set about intercepting Fearling attacks and trying to open paths toward the sleigh for the others. She felt her grip of the skipping stones spell loosening and released it, filing that away as another thing to work on when they got back to the Pole. The roller coaster golems were plenty to control right now anyway.
