Earth on Turtle's Back Theme/Tone

The theme for Earths on Turtle's Back was size doesn't matter and work as a team to achieve your goal. The muskrat got to the bottom and he was so tiny and no one believed and him but he said he was going to touch it no matter what he had a goal and he ended up achieving it. The tone is kind of suspenseful because of how we don't know what going to happen with the Sky Women.
