Frances the Hedgehog? My daughters loved those books. I found one here:

Frances is a badger, which as an adult I find odd, because badgers are nasty little creatures.
I liked the Frog and Toad books, too.
But my absolute favorite book was Mike Mulligan and His Steam Shovel. I felt so bad that the new machines were mean to Mike. LOL
There was another book that I cannot remember the name of and seems to have fallen off the face of the earth. It was about a private eye who had a case about a missing elephant at the zoo. The elephant stole ice blocks from the penguins and went to visit his family.
