Oh it's a sweet, sweet world

Cadbury Bournville released an online ad in 2013 that featured a screamer.

Ad
The ad begins peacefully, showing footage of evening skies as a quiet piano piece plays. Eventually, the ad moves on to footage of babies giggling and playing with each other. However, at the 0:26 mark, Regan MacNeil pops up, though her usual scream is mixed with other screams this time. The ad ends with a message telling the viewer to have a happy Halloween. It was part of the #NotSoSweet campaign.
