The Ululu Company

Background
The Ululu Company, originally founded as The Curiosity Company, is The Simpsons creator Matt Groening's independent production company, known for producing the animated series Futurama for FOX and Disenchantment for Netflix, as well as the Christmas special Olive the Other Reindeer. The company was launched on April 21, 1997, but did not use a logo until 1999. In 2018, it was renamed to its current name.

(March 28, 1999-September 4, 2013)
Nicknames: "The Water Reflection", "The Surfboard Reflection", "A Study in Wet Logo"

Logo: Against a black background, we see the silvery flickering words "THE CURIOSITY COMPANY" arranged in three lines underneath a square. Above it is a heavily distorted image of wavy lines, waves washing ashore or golden dots on the water, which varies depending on the episode. In the first two versions, there is a "C" shape made from a distorted surfboard reflection in either fully red or red with a white copy on it. On the second version, the distorted surfboard "C" shape appears to move down, with copies connecting them. The "O" in "CURIOSITY" has a dot in it (a la the HBO logo).

Trivia: The water rippling footage (and the accompanying audio) is taken from a short film named A Study in Wet, made by Homer Groening, Matt Groening's father.

Variants:
 * On the first three episodes, direct-to-video movies and seasons 6 and 7 of Futurama, the words "in association with" are shown below the logo.
 * There's also a still and credit-compressed version of airings of Futurama on Comedy Central.

FX/SFX: The waves (live action), and the lines and text flickering.

Music/Sounds: Either a heavily distorted rippling sound or a heavily distorted sound of waves washing ashore, depending on the episode.

Music/Sounds Variants:
 * On the Futurama episode "A Taste of Freedom", Bender (voiced by John DiMaggio) is heard saying "Freedom!" after the final rippling sound.
 * On the Futurama episode "Bender Should Not Be Allowed on T.V.", Hypnotoad's signature noise is heard instead.
 * On digital prints of the first two episodes of season 1 of Futurama, it's silent.
 * Fox airings of Futurama (starting in 2002) used a generic theme.

Availability: Common. Seen on Futurama and Olive the Other Reindeer, both of which are found on DVDs and VHS tapes. Don't expect this to appear on The Simpsons episode "Simpsorama", though.

Legacy: This logo is known for disturbing some due to its weird noises and psychedelic patterns.

(August 17, 2018-)
Nicknames: "No Curiosity", "The Puzzle"

Logo: On a white background, we see what appears to be "ULULU" designed like a puzzle, in red. Above and below the text is "THE" and "COMPANY" in green. The logo is glitched, displaying extra colors, mainly yellow.

FX/SFX: None.

Music/Sounds: The closing theme of the show. On the 10th episode of Disenchantment, it's silent, as it's one of two episodes that contain an after-credits scene. The other episode, the 40th in number, has the end theme continue playing over its after-credits scene, thus playing over the logo as well.

Availability: Seen on Disenchantment.

Legacy: This logo is way tamer than the previous logo, but it isn't as iconic. It doesn't look like it's supposed to be iconic, anyway.
