I got this idea from a video I saw on YouTube...
It's all about a mayor who is trying to get to know the people in his new town. Except, they all look the same and have the same name... The mom's name is Hundreds. The little boy's name is Tens. The dog's name is Ones.
So he finds out their last names: Billions, Millions, Thousands, Units.
Then he builds a Pond (named Decimal Pond) and it attacks a bumble bee named Tenths and a bug named Hundredths.
