When talking with the Plant Express ship, Leela is seen in her pajamas. However, when the ship became crazy and turned off the oxygen, Leela grabbed her oxygen mask. When in the shower talking with Bender and Fry about her plan, she is seen in her Valentine's uniform.
When Bender dumps the Planet Express ship, the PE ship comes to a screeching halt, as seen from the outside of the ship, but when the scene goes back inside the ship, the stars are still moving outside the window.
When Bender is talking to the newly discovered female voice of the ship about the radio setting, she says "Remember Bender, we each get one of the four buttons, that was the deal.", but there are 5 buttons.
