It's fireworks. They're having a party~
They're not very important character-wise.. in fact they barely rate the Minor character moniker. It's about a little girl who's ship crash lands on a planet... and her parents die, so she is raised by.... a bunch of aliens.. Including a transforming mecha that's kind of "slow" and a giant purple furball cat creature. And..a walking brain+spinal cord.
...That should be a pretty big clue.
