Visuals: On a black background, a scribble path is drawn from the top left to bottom right, forming a mostly filled in box. Afterwards, a and white sketch of a happy cartoon bear with a furry outline pops within the centre of the box alongside " Humphrey Barclay Productions ", its co-producer's name, and the copyright notice in a  Dom Casual font underneath.

Variants:
 * There is a later variant where the bottom text portion is altered. Two horizontal lines coloured and  are placed over and underneath the same set of text but in a capitalized font.
 * This variant would be set on a white background in its last few years.
 * On Porkpie, the title character's hat falls from the top, leaving a path along the way, and lands on the bear's right ear.
 * On the Desmond's episode "O Little Town Of Peckham", a Christmas-themed variant is used where the bear is wearing Santa's hat on its left ear.
 * On Up the Garden Path, the only text present is the company name in a regular font.
 * On Agony Again, this logo shares the screen with the 1988 BBC logo.

Technique: 2D computer animation.

Audio: A pencil scribble sound effect, followed by a high-pitched chime note.

Audio Variants:
 * Sometimes, the ending theme of the programme may play over.
 * On Porkpie, the title character utters a line similar to "He hu-muh!" while the logo forms.
 * On the Desmond's episode "Judgment Day", a loud and hard laughter is heard for the logo's formation.
 * On the Desmond's episode "O Little Town Of Peckham", the Christmas-themed variant has Santa laughing in a fairly goofy fashion.

Availability:
 * Seen on Desmond's, Porkpie and Agony Again, among many other programmes at the time.
 * They are intact on television airings old and new as well as on streaming services such as Tubi.
