Spring is a celebrity chaser who appears in Professor Layton and the Unwound Future. She is the only person who can work the giant "time travelling" clock apart from her husband, Cogg. She co-owns the clock shop on Midland Road in London. Near the very beginning of the game Spring shuts and locks the door behind Layton and Luke as they run out of the Clock Shop. In the game, she is found inside of the Clock Shop, usually in the first room. She is the first person "from Future London" in Unwound Future Professor Layton and Luke meet.
Spring gives Layton and Luke a single puzzle. She can be talked to earlier on in the game and she gives the puzzle "Needling Needles".
