There is a song in the U.S. that is popular at summer camps and other places--one of those songs that builds up a line at a time and is sort of a memory game for the people singing it.
Oh, the tree's in the hole
And the hole in the ground
And the green grass grew all around, all around
And the green grass grew all around.
Each verse adds a detail:
Now on this tree
There was a limb
The prettiest little limb that you ever did see,
Oh, the limb's on the tree and the tree's in the hole
And the hole's in the ground
And the green grass grew all around, all around
And the green grass grew all around.
The final verse goes
Oh, the flea's on the feather,
And the feather's on the bird,
And the bird's in the nest,
And the nest's on the leaf,
And the leaf's on the twig,
And the twig's on the branch, <-----
And the branch is on the limb,
And the limb's on the tree,
and the tree's in the hole
And the hole's in the ground
And the green grass grew all around, all around
And the green grass grew all around.
Here's a version by the late great folksinger Pete Seeger:

He gets to "the twig's on the branch" at about 1:02
