Jumbo Pictures

Background
Jumbo Pictures, Inc. was an independent animation production company founded by animator/children's' book author Jim Jinkins (creator of Doug) in 1988. In 1996, Jinkins sold the company, and the rights to Doug with it (except Nickelodeon still owns the rights to the Nick-produced series), to The Walt Disney Company. Jumbo Pictures continued operations until the cancellation of the Playhouse Disney cartoon series PB&J Otter in 2000, and was folded into Walt Disney Television Animation after that. Jinkins is still active in animation, forming his current production house "Cartoon Pizza" in partnership with David Campbell in 2001.

Nicknames: "The Egg II", "The Jumbo Egg II", "The Doug Logo II"

Logo: On a vanilla cream colored background, we see a large egg with "JUMBO" in front of it. Below it are the black text "PICTURES" and "INC.", both in smaller fonts. The surrounding area dims as the egg's shadow becomes visible, and the text "GRADE A QUALITY" fades in below the egg.

Variants:
 * In 1999, the background became light blue. This was first seen on split-screen credit airings of Disney's Doug when aired on Disney's One Too.
 * On Disney's (Brand Spanking New) Doug and PB&J Otter, the logo is shifted up a bit and there is a copyright stamp under it.
 * On the 1999 film Doug's 1st Movie, the egg is smaller and the background is a different shade of light blue. Plus, "GRADE A QUALITY" is a bit bigger. The egg is also more realistic and there's no copyright stamp below.
 * On 101 Dalmatians: The Series and Sabrina: The Animated Series, an in-credit version of the logo is used (text only).
 * On Doug's Big Game for the Game Boy Color, the logo is smaller and on a white background. "GRADE A QUALITY" is also in red.
 * On Allegra's Window, the animation is slowed down, and on Season 1 episodes the logo is darker.

FX/SFX: The shadow animation.

Music/Sounds: Either the closing of the show's theme or a snippet of background music from Doug consisting of a synth organ and muted trumpet-like vocal humming (composed and performed by Fred Newman).

Music/Sounds Variants:
 * On Allegra's Window, it was a dramatic rendition of the song "What a Wonderful Day" accompanied by a rooster crowing.
 * On Doug's 1st Movie, you can hear a sampling of the Disney's (Brand Spanking New) Doug theme music.
 * At the end of the Nickelodeon Doug episode "Doug's Christmas Story", a rendition of "Deck the Halls" plays, going into "Jingle Bells" once going to Ellipse Programme and the Nickelodeon Productions logos of the time.
 * At the end of the Nickelodeon Doug episode, "Doug Throws a Party/Doug Way Out West", the music is delayed on some airings.
 * During airings of Disney's Doug on Disney's One Too with split-screen credits, the 1988 music for the second Walt Disney Television logo would play over it, also going into the said logo.
 * On NickRewind's airings of Nickelodeon's Doug with the split-screen credits from 2011 until 2015, the beat-boxing tune was abridged in order for it to end on this logo so it wouldn't play on the 2009 Nickelodeon Productions logo that plastered the usual NAS "Haypile" logo.

Availability: Common. It's currently seen on Doug as part of NickRewind on TeenNick and on the Disney episodes on Disney. It was also seen on PB&J Otter when aired on Disney Junior and the short-lived series Hoyt'n Andy's Sportsbender. Home video releases of Doug, Allegra's Window, Doug's 1st Movie, and The Beginners Bible keep the logo intact. The dark blue background variant was seen on season 1 episodes of Doug, which is now available on DVD and is currently seen on split-screen credits of said show on Teen Nick. The in-credit text version is rare, and can be seen on 101 Dalmatians: The Series, which last aired on Disney Junior in 2013. However, episodes can be available to purchase on the iTunes store, as well as streamed on Disney+, and is also seen on the show's VHS release 101 Dalmatians Christmas.

Editor's Note: Same as the last logo.
