• Wolfoo is the protagonist of the show. He is five years old, and belongs to the Wolf family. Superman is his favorite character. He is kind and smart. He sometimes apologizes when he makes mistakes and his catchphrase (utilized at the end of an episode) is "Awooo!" like a wolf's howl, the same as his little sister Lucy.

• Bufo is one of Wolfoo's friends. He comes from a wealthy family. He is a bully to Wolfoo and his friends but apologizes and learns his lesson.
• Piggy is Bufo's best friend and sidekick at bullying, though like Bufo he sometimes learns his lesson. He comes from a agricultural rural family and treats Bufo like a "big brother".

The voice actors of the characters in the show has been not revealed.

The first official episode of Wolfoo was published on August 23, 2018.^{[citation needed]} Several Wolfoo channels were launched on YouTube; some examples are "Wolfoo America", "Wolfoo's Stories", "Wolfoo Shows", and "Wolfoo – Sing Along Songs". This is similar to a method used by other content farms.^{[citation needed]} A series of feature-length online films, such as Wolfoo the Adventurer, were also released on YouTube. A spin-off, Bearee, was released on April 16, 2022.^{[2][failed verification]}

The show is available on 40 VOD (video on-demand) platforms in China, and was later released in Chinese children's TV networks due to SConnect's deal with its Chinese market partner Leadjoy, with SConnect producing and releasing a 3D version of the cartoon.^[3]

In October 2023, a movie named Wolfoo and the Mysterious Island (Vietnamese: Wolfoo và hòn đảo kỳ bí)^[c] was released, which premiered on Vietnamese cinemas and entered box office revenue as the top 3 after one week,^[4][5][6][7] but the full film was not uploaded internationally.

Wolfoo has also been criticized for its usage of gross-out humor throughout its run, constantly featuring animated depictions of defecation and or urination by several characters, pregnancy and anthropomorphic organs. However, this type of videos which the show got criticized is similar to Elsagate, a controversy concerning a genre of animated children's videos in YouTube. It has been accused of copyright infringement by the creators of Peppa Pig, and the show's distributor, Entertainment One, has sued SConnect for Wolfoo's visual and aesthetic similarity to the show.^{[8][9][10][11]}

On January 24, 2022, Entertainment One filled a case against SConnect at the High Court of Justice as follows: rework of Peppa Pig characters, using the art style of Peppa Pig, using the exclamation sounds of Peppa Pig in 91 Wolfoo videos; causing unfair competition, causing the misunderstanding that Peppa Pig and Wolfoo share the same owner and violating the trademark of Peppa Pig.^[12]

In November 2022, the Authority of Broadcasting and Electronic Information requested Google to look and resolve the issue of Wolfoo episodes being deleted on YouTube by Entertainment One's ongoing copyright strikes. After the intervention of Vietnamese authorities, YouTube reopened the YouTube channels of the show; however, 4,000 videos of the show have yet to be relaunched.^[13]
