Lost legs?!

[HermieGuy]

Hey, I just checked on my tank as I was getting ready to go to bed, and my hermit crab Scuttle had gone back underground... and I found two crab leg pieces in the sand?!

I don't know why they came off or if Scuttle is okay. I didn't disturb the area where Scuttle dug down, but I think this might be something to do with his recent molt?

I've located Scuttle and he's alive, but all I did was mist him with freshwater a bit. He moved, but I looked at the leg pieces I found. Two were actual leg pieces and one seemed to be the lower part of the big pincher claw. These are actual parts, not hollow parts left behind from Scuttle's recent molt.

I have no idea if Scuttle is okay or if loss of limbs is normal just after molting.

HOLD ON, I think Scuttle is fine. I took a closer look at the parts I found and they looked real. It turns out that they weren't, because Scuttle came back up just now and he had all his parts. I do know that the parts I found were from Scuttle, because my other crab is much smaller and wouldn't have grown that quickly.

I guess I just can't really tell the difference between left-behind exos and real hermit crab parts. Sorry about all this, I came here in a panic...
