O Entertainment is a production company founded in 1990 by actor Steve Oedekerk. The logo usually appears at the end of The Adventures of Jimmy Neutron: Boy Genius.
It shows a huge purple bouncing letter "O" while a low-pitched voice saying "O!"
Cheesy Factor Edit
Very cheap and corporate animation.
Scare Factor Edit
None to low. The black background, a deep voice saying "O!", and the "O" falling down without any type of warning may startle a couple people, but it's not that big of a deal. For unfamiliar people, low (or medium) to high.
