Hi there! I’m seeking Stump the Bookseller’s help in finding a lost book from my childhood. It was about a white, blobby creature that came down to the earth from the moon and had adventures. This book was available in the Huntingdon Valley Public library in the Philadelphia area in the 90s (I’ve looked there and asked the librarians without success) but I’m sure it was not self-published. It was a picture book or perhaps an early-reader chapter book (I believe it was portrait orientation) and I think it was part of a series. It was illustrated–if not fully illustrated–on the interior. It was not new in the 90s–it had a slightly vintage feel–perhaps 60s, 70s, or 80s. The art style was graphic and cartoony–more akin to the Space Case books by Edward Marshall than something illustrative like Moornhorse by Mary Pope Osborne (and no, it’s not either of these–It’s also not Moon Man by Tomi Ungerer, the Matthew Looney series, or Dmitri the Astronaut by Jon Agee.) There were themes of loneliness–perhaps the moon creature came down to earth to make friends? It’s possible he was not from the moon but rather a different planet. I believe the background color of the cover was black. It’s possible that this unsolved query is describing the same book: http://w1.loganberrybooks.com/stumpthebookseller/145x-moon-creatures/. [EDIT: I now believe this is a book in the Moonbird series called The Unicorn and Witch. I don’t think it’s the book I’m looking for, though.] My mom remembers the moon creature as having had a pear-shaped body, maybe a bit of neck, and then an oval or round head, whereas I more clearly remember a white horse or perhaps unicorn. There could have been a little boy protagonist too, but I don’t remember clearly.
