They may have had front legs. The back legs were not much bigger than eyelashes,
so they could have been hard to see. I imagined them being larger before they
left.
I kind of thought they'd hang out around the pond a bit, too, but its been raining
for a week and I know the frogs move about more when it is raining.
I hope they're ok. They sure were cute.

Usually they have their back legs a while before they get their front legs.
After their front legs appear it takes about two days to absorb their tail and
they take off.

Predators for tadpoles are birds, snakes, bullfrogs, some insect larvae. (No
fish in the pond I'm assuming.) A predator may have visited their little pond
if you didn't see any front leg development.

They sound like toad tadpoles and they do change rapidly.
