On a dark dark hill
There is a dark dark house
And in that dark dark house live...
The Big Skeleton, the Little Skeleton and the Dog Skeleton.
Or is it the Big-Elephant Skeleton, the Little-Fish Skeleton and the Dog-Snake Skeleton?
You decide with this brilliant mix-and-match puzzle along with the classic Funnybones tale. Match up the Big Skeleton's head with an elephant's body, or an elephant's head with the Big Skeleton, or whatever combination you like!
