In the Field Guide Arc
- Nettlepad, on his vigil, alerts the Clan that a fox is trying to get into the nursery and Lightningpelt and Molewhisker, also on their vigil, chase the fox away. Lightningpelt proudly states that the fox won't come back in a hurry, but Fernleaf then warns her that foxes have a habit of coming back once more before they decide whether or not to settle. Fernleaf tells her and Molewhisker that they would need to be ready to chase it off again should it come back.
