Hermit Crab Molting Questions

[ChonkyCrabsLover]

Hello, today when I woke up I saw that BOTH of my crabs decided to molt. However, one of my crabs is already out of his burrow and done molting by around 11AM. He wasn't just testing the burrow either like I have seen my crabs do before, because he was fully submerged and he covered his hole back up after he went in. I have no idea how my crab is already done molting in under 12 hours. My crabs have had a history of molting very quickly, but this is insane being done in that much time. Everywhere I look it says it will take weeks or even months for a crab to molt. For the size of crab I have, it should take 3-6 weeks. Does my crab just like digging? I feel like he wouldn't cover his hole back up or spend that much time in it if he was just digging. My crabs seems a darker purple color and his legs are hairier than normal, so I guess he did molt? Does this make sense to you?
