"Do a shoey" is an Australian practice of drinking quickly ("skolling" in Australian parlance, "chugging" for Americans") a beer or other alcoholic drink, out of your shoe. Obviously not something that's going to be in a children's movie like Paddington.

The source of this error is obvious. There's a YouTube clip of Hugh Grant and Jimmy Fallon doing a shoey. The video's title is 'Hugh Grant and Jimmy Chug a "Shoey" (Drink Beer from Their Shoes)', and its description also says "Hugh Grant reveals how his casting as the villain in Paddington 2 was so spot on it crushed his pride a little".

The source of the error is obvious, but no human could ever make it, and it's proof that AI should not be used to replace basic search engine functionality.
