Pluto is jealous of neptune
Is it normal for a dwarf planet to be jealous of a real planet? What if Pluto decided to go off and attack Neptune or something. I mean, cmon their orbits intersect. And ever since Pluto was declared a dwarf planet, you'd think it would be a little bitter. So it would be logical to think that, when lashing out, Neptune would be the target of its random violence. Just imagine Pluto waiting hundreds of years for its chance to crash into Neptune.
Pluto: "We've passed eachother 12 billion times already, but I can feel it, this time I'm gonna hit that motha fucka! Get ready Neptune, here I come!"
Neptune: "Get over it already, damn!"
