There are a bunch of adorable space critters that you’ll think are that when you’re watching the movie, and they certainly were marketed and merchandised like crazy, but they’re actually there due to the unwanted presence of adorable Earth critters during filming. They couldn’t shoot the scenes without including these birds that lived where they were shooting so the solution they came up with was CGI-ing weird faces on them and including some close-ups to make them look deliberate.
