A fantastic hat that turns the child's head into everyone's favorite robot R2D2.
R2D2 is an astromekdroid that plays a major role in the Star Wars movies and where he usually appears along with his robot friend C-3PO.
In episode I, R2D2 belongs to Naboos royal family. He was then on the space ship that the royal house fled Naboo in and when the shield generator hit and damaged the ship, it was R2D2 that repaired the damage.
Similar roles have R2D2 in several of the remaining films and save the main characters on several occasions. Maybe R2D2 is one of the Star Wars series disrupting heroes?
