The rest of the class seems to be in no rush to grow up, and that's fine by me.  The younger members are now around the age the older ones which were getting their front legs out, and I see little to nothing indicating back legs are forming yet.  These guys might be Green Tree Frog tadpoles.  

The 4th Amigo decided to wear a leaf hat(and a short video clip of it):

I also did some more videos. I knocked down the FPS to 30, allowing more light per frame.  Video is a bit less smooth but you can see the tadpoles better.

First clip is of the 4th Amigo.  If you watch closely you can see small particles going into his mouth so while it appears that he's just doing nothing, he's apparently eating. Second clip is some of the other class members.
