Wolfoo, the popular children's animation series, has been found guilty of copying Peppa Pig, as a high court judge ruled that the Vietnamese makers illegally used audio clips from the famous cartoon pig. The copyright infringement case, brought by Hasbro, owner of Peppa Pig, has resulted in an order to remove all Wolfoo videos from online platforms like YouTube.
Hasbro Wins Copyright Battle Against Wolfoo
The US-headquartered entertainment company Hasbro, which owns the rights to Peppa Pig, sued SConnect, the Vietnamese makers of Wolfoo, for using short audio clips of Peppa and her family saying words like “Hooray!” The judge described the copying as “prolific” and “longstanding,” with compelling evidence of audio clip copying. The court ordered all Wolfoo videos to be removed by 4pm BST on Monday.

Details of the Court Ruling
The high court judge in London examined 92 English-language Wolfoo videos and found sound clips from Peppa Pig in all of them, and in 75% of foreign-language videos. SConnect had denied the claims, stating that an independent third-party contractor used the sounds without their knowledge, but the judge dismissed this as “irrelevant” and disproved claims that later videos used original sounds.
Impact on Children's Animation and Copyright Law
This case highlights the importance of copyright protection in the animation industry. Wolfoo, which has hundreds of millions of views online, including on YouTube Kids, targeted children aged two to five. The court's decision reinforces that copying audio or other creative elements is illegal, even for popular content.
What This Means for Content Creators

Content creators must ensure they have proper licenses for any audio or visual elements used in their productions. The “independent contractor” excuse did not hold up in court, emphasizing that the primary producer is responsible for copyright compliance. This ruling sets a precedent for future cases involving similar content.
