Yes, SetterGuy posted about the beautiful symphony the American Toads make when they all hop in the water and call for a suitable mate. We had that great sound for a few nights, and then temps dropped and everything nearly froze. Once things warmed up again a few more toads made it into the pond and laid eggs but we really had an 'off year' for that. They look like ordinary toads and all come out of the woods, hop in the pond for maybe 2-3 days max, then all take off again so not sure the LMB have a lot of time to eat them or could keep up with the sheer numbers when they all make the migration at once.

The 'toad-poles' are jet black as in the video above and for a short time the sandy in the shallows is eaten clean of algae. IF they only stayed in the pond all year! But they all eventually grow legs, shed the tail, and then all of them as on a cue leave the pond together and struggle to all hop through the grass back out in the woods again.
