Miko's Party Kit

Miko's Party Kit is a large box of fireworks which Miko has been saving all year. The largest firework contained there is The Big Banger.

Titan Prime comic
Miko foolishly left the Party Kit sitting on a table next to the sofa the kids used to watch television. When Soundwave's disembodied hand attacked Bumblebee, Raf grabbed The Big Banger from the box and taped it to the rogue appendage. The firework carried the hand high into the sky and exploded. It was seen by the returning Miko, who demanded to know why Raf was setting off her fireworks.
