The best pal to have at the end of the world

Humpy's dumpy sat on the ground,
Humpy's dumpy wiggled around.
All the incy wincy limbs,
Lifted Humpy's tiny grins.
Faces beamed with extra glee,
Staring around so happily.

Friends grouped from their den
Together they sang, "Let's play again,"
All faces smiled so bright,
Bringing joy day and night.
