It’s looking like “Finding Dory” will go down in the history books as industry experts estimate that it will earn around $115 million to as much as $120 million, the biggest box office opening weekend for any Pixar movie.

The sequel to 2003’s “Finding Nemo,” which brings back Ellen Degeneres and Albert Brooks, tells the story of a Pacific blue tang that suffers from short-term memory loss.

“Finding Dory” represents a financial bounce back for Pixar. The animation studio’s last movie, “The Good Dinosaur,” fell flat in November, only earning $55.6 million at the opening weekend for a worldwide total of $331.9 million. Before that, all released Pixar films have grossed more than $350 million worldwide, Variety reported.

The movie will also represent another commercially successful entry from Pixar’s parent company, Walt Disney Pictures. Global cumulative 2016 ticket sales for Walt Disney Pictures alone has reached $4 billion, mostly due to “Captain America: Civil War,” “The Jungle Book” and “Zootopia.”

In other news, biologists and scientists are reminding fans of “Finding Dory” that the Pacific blue tang doesn’t actually talk and it should not be kept as a pet.

“When you make an animal charismatic, adorable and just as cute as it is with Ellen DeGeneres’ voice on there, there’s nothing you can do to stop people from wanting to know more about that animal and then wanting to be able basically to keep that as a pet,” Andy Rhyne, a marine biologist of Roger Williams University, told Marketplace in an interview.

An online petition has also been started around the cause, which has almost reached its target goal of 110,000 signatures, the Business Insider reported.

The writer of the online petition, Kelsey Bourgeiois, has referenced an alleged 40 percent increase in the sale of clownfish after the theatrical release of “Finding Nemo” as a precedent basis for the fears.
