The remaining two "Pond" Spadefoots passed away yesterday.  Earlier yesterday, I noticed a Spadefoot  that appeared to have passed away.  I scooped him out and put him in another container just in case.  The fella recovered and was even climbing a bit. I named the fella Second Chance (first photo below.) Sadly when graduation time came around later on in the day, Second Chance wasn't doing so wall.  He apparently needed a third chance.

The other one appeared alive and well before I went to bed and this morning the fella also passed away.  

The other class members seem to be doing well. I have a photo and video below of the "Originals" group and "Three's a Crowd" group.:
