I think the best way to put this is that their size depends on the size of the frog, but they are black or brown, smelly and contain indigestible insect parts, eg. moth wings, beetle shells, grasshopper legs. They look like little rocks but if you look at them closely you can tell that there frog droppings :)
Maybe it was a sick hobo.
Deer droppings
YES, because a mole is brown like mouse droppings
American cockroach droppings look like little small round balls.
Chipmunk droppings do look like mouse droppings. It can be difficult to tell the difference between the two. However, chipmunk droppings are a tiny bit larger.

Lizards typically have white tips in their droppings, which are composed of uric acid, a waste product that is excreted instead of urea, as reptiles do not produce liquid urine. In contrast, rat droppings are generally dark brown or black and do not have a white tip. Therefore, if you observe droppings with a white tip, they are likely from a lizard.
Their droppings will be wateringWatery doodie.
They look like dry coffee grounds
The droppings are the same size and shape as a grain of rice, and they are very dark brown.
the ondontochelys look like turtles and a lizard
Not exactly. Elk have droppings that are a little bit larger than the droppings you'd find from deer. They do look similar (as they are both in the form of droppings) but size is the big differential.
