They decided to do all of the ideas, they did it for a long long long time, but it wasn't too too effective, they came up with a really evil plan a million years later. They came up with the idea to bump into her, Since she was the most valuable and breakable, it was really effective.
How Pluto became a Dwarf Planet
A long time ago before Earth had life inside of it, Pluto was the biggest planet, even bigger than the sun, way bigger than it actually. All the planets were jealous of her and wanted her to be the smallest planet and Jupiter to be the biggest planet. they knew it would take a while but they came up with a few plans to achieve their goal
We should summon space worms and train them to eat Pluto
We should tell Milky Way Guardians she has to pay with parts of her body
We should tell space theft to steal parts of her body.
Oh No! Now I'm the smallest planet!
They didn't stop until people on Earth had gotten the ability to see into space, for a long time the people counted Pluto as a planet, and then they decided she was too small. The humans on Earth decided to call Pluto a Dwarf Planet. She was way happier now.
