Lake Rodney With every small disaster

I have no impulse control and have wanted these two for a whileee

When Fennec left Niamh, rather than going straight back, she made the trek out of the territory and towards the lake.  There were few herbs left in the winter cold, but those few would likely be found there.  Willow.. maybe some frozen plants beneath the water.  She found the bark relatively quickly, but pawing at the edge of the lake had turned up nothing so far.

She picked up her stack and wandered on, feeling the snow turn to ice as she stepped (by accident) from shore to glassy lake surface.  It was frozen solid.  Her paws tingled from the numb and she stepped back, then dropped her bundle.  She should get back and check on Alyx and Bronco.  Their wounds likely needed some attention again.  She'd kill for some marigold, though.  What else helped infection?

She paused, considering it a moment.  Was there anything resilient, like the bark, she could use?
