Helme Heine was a best-selling German writer, children's book author, illustrator and designer. He lived in New Zealand, writing screenplays, audiobook scripts and creating satirical drawings and sculptures.
A rooster, a pig, and a mouse hang out, being friends, at a place out in the country called Mollywoop.
There is no overarching story, just vignettes, as each two-page spread is its own little episode, told in rhyme, about cycling, archery, playing dress-up, taking baths, and other random and inane topics.
This book was a gift from relatives with dubious taste to my daughter when she was four. (A sticker left on the back suggests it was fished out of a remainder bin.) As with most of the picture books they gifted, she had no interest in it, and we never revisited it.
It turns out the book is the sixth in a series of picture books from Germany about these three friends. Auf Deutsch they are Franz von Hahn, Waldemar, and Johnny Mauser; in America they are Charlie Rooster, Percy Pig, and Johnny Mouse.
For those sensitive to body image, Percy Pig is pretty consistently called "fat Percy" throughout. For those sensitive to torture, the three friends tie a fourth friend to a stake for shushing their loud play, "And left him standing there all night," with no repercussions on them.
