Jeremy Fisher is a frog. He lives at the edge of a pond in a "slippy-sloppy" house. One day he paddles off across the pond on his lily-pad boat on a fishing trip. He encounters all sorts of problems, not the least of which is a large trout who tries to swallow him. He ends up swimming for shore, and resolves not to go fishing again.
Glenn Hascall does a beautiful job narrating this classic by Beatrix Potter.
