It was a middle-grade reader, I think. Kind of goofy and spooky, with monsters and toys that came alive. I specifically remember some army men coming alive to fight a monster. Pretty sure the protagonists were two siblings, a girl and a boy.
Any ideas? I wish I could remember more, I listened to it as an audiobook in the 90’s or 2000’s in the US, I’m pretty sure it was new-ish then so maybe published in the 80’s or sooner?
This isn’t it, but thanks for the suggestion!
Darn! It checks all the boxes, it might have been a book riffing on the movie’s success. Good luck!
