Quicky is a rabbit character that Nestlé's chocolate-focused brand Nesquik uses as their official mascot. The mascot made his debut in 1973. Quicky's cereal box appearance and given name evokes associations with speed and easiness within the consumers mind. The animal choice of rabbit is not a coincidence, but rather a clever choice, since rabbits are known for their speed. In the TV commercials Quicky's voice acting work is done by Barry Gordon, but sometimes also by other male actors. The mascot's outlook was somewhat redesigned from 2005 and onwards to appear more detailed and modern.
