It turned out the “mystery attacker” wasn’t dangerous at all, but an unexpected nighttime guest: tree frogs. Drawn by moisture and warmth, these tiny acrobats climb smooth car surfaces with their suction-cup toes, leaving delicate, ghostly trails behind. In the cold light of morning, those faint, dried marks can look like something far more serious—scratches, animal prints, even signs of forced entry—when in reality, they’re just the footprints of a harmless visitor passing through.

Once you know, the fear melts into a strange tenderness. A quick wipe with lukewarm water is usually enough to erase the traces, though the story tends to linger much longer. Parking a little farther from dense bushes or overhanging branches can reduce these surprise encounters, but perhaps it’s no bad thing to be reminded that our cars sleep outdoors, in a world still quietly shared with small, wild neighbors.
