This book was one my sister and I read in the 1970’s to early 1980’s. I recall that there was a forest creature (cannot remember what kind) who possibly (moved?) to a new house in the forest with a red door. I think his friends were supposed to wake him up for some reason but then they couldn’t find his house with the door, because it was covered with a fallen tree (?) or maybe snow(?). I think they kept finding red things that didn’t turn out to be the door. It would have been a shorter children’s story with a lot of pictures. We read it in English.
