Maybe I'm just missing the joke, but Wikipedia says otherwise
"As of May 3, 2026, The Super Mario Galaxy Movie has grossed $403 million in the United States and Canada, and $495 million in other territories, for a worldwide total of $897 million. Produced on a budget of $110 million, the film is currently the highest-grossing film of 2026 and the highest-grossing animated film of the year. The film also set the record for the biggest global opening at the box office in 2026, the only animated film franchise with two films opening to over $350 million globally, the fifth-biggest global opening for an animated film of all time, the second-biggest global opening for an Illumination film, the second-biggest opening for a film based on a video game, and the fourth-biggest Easter three-day opening of all time."
Almost $900 million gross against a cost of $110 million seems pretty good
