Just spoke to her a few mins ago and he seems fine now. She said he's a little skidish but that's to be expected I would think since he woke up/came too in a box for a few hours.
I told her to keep an eye out for any signs of illness like you all said so shes doing that. I honestly think the thing was that he just flipped himself upside down and started to drown and luckly she took him out while he was passed out thinking he was dead, then came too later on. I think the reason he passed out though was due to being upside down and taking in water rather than an illness, but she's still keeping an eye on him just to be sure.
The good news is he seems to be doing fine so far. She's getting him a dock tonight so she can get rid of the rock that's in there.
