SOLVED. Children's book about animals on a raft trip [s]

[Syd]

This was a book I was obsessed with in my childhood. I used to carry it around. Please help me find it! I've been trying for years.
It was a small mammal and a rat or mouse I think on a raft trip down the river. I think the book was fairly long for a picture book with chapters about different stories on their trip. There's a race, and they eat peppermint at some point, and a gatekeeper for the river is talked to (I think he's a larger mammal or rodent). Also they rescue an animal baby from the river I think?
I thought it was called something like animal tales but I don't think that's true. It may also be some version of wind in the willows? Though I know the book is centered around the raft trip.

Could it be something by Arnold Lobel? The only one I've read is "Frog and Toad" but I think he did other small animals too. And his books are hellishly long, for picture books...they're more like little chapter books for 6 year olds. He does have one called Mouse Tales. I don't know if it involves a raft trip.

[Syd]

No, it's not Lobel I don't think. None of the titles by him look like it's it, and it's not the same art style. Mouse tales is definitely not it. Thank you, though!

Have you reread Wind in the Willows to see if a section of it matches? This sounds really familiar.

[Syd]

I have never read the wind in the willows. If it's related, then it's some sort of spin-off. I looked through a copy the other day and none of it seemed familiar because the book I'm thinking of is exclusively focused on the raft trip and it's not as long.

When I was a kid, we had a picture book that turned out to be part of The Wind in the Willows, and I just looked at Kenneth Grahame's list and there are several series of excerpts from the book published separately. You might want to have a look.

I'm going to guess that it's the River Bank and other stories. I'm going to obtain a copy and see if it matches up with what I remember. I can always move it back to unsolved. Thanks everyone for their help!
