Before Fry and Leela are mugged, the Pi-KEA trailer is just behind them. But in the next shots when they are mugged, suddenly it has dissapeared behind them.
The miracle cream is said to work "on humans". However, Leela isn't technically a human. She is a mutant, which are deformed humans. Evidently she is human enough to allow the cream to work on her though.
On the πkea box is an ø. However, this character is not used in the Swedish alphabet. It is only used commonly in the Danish, Faroese and Norwegian alphabet. More correct would have been an ö. However, the same 'mistake' is made in the subtitles for the opening credits of Monty Python and the Holy Grail. As such, it may be an allusion rather than a goof.
When announcing on the Planet Express tower about the new super heroes Leela's gloves are visible. But when she whispers "A new era of justice has begun" her gloves have disappeared.
When leela was confesing to her mom and dad she ripped of her normal clothes to reveal that she was Clobberella and then later on she had ripped her Clobberella suit so that she can wear her normal clothing wich is strange because the Clobberella suit has less coverd area than leela's normal clothing wich only shows the head and neck area and her arms and her Clobberella suit shows mostly anything but the vunerable part's in a girl's body and her stomach
