Corrected entry: When Carly and Freddie are frantically trying to find a birthday present for Principal Franklin, they are talking in the kitchen and you can see a microwave above the sink. Carly then runs to the counter and grabs a microwave to give to him. Why would they have two?
Corrected entry: They yell at the lamp, "Rampu," but the right word is "Rampuu," with an "R" that sounds like "L" and the U's are silent, so it sounds like "Lamp."
Correction: Actually, in Japanese the word can be either be pronounced as L or R. It all depends on romanization. And for the ending, it's not silent. It's just not as enunciated loudly like in English. Same goes for Korean and Chinese: sounds are shortened.
Correction: There is no visible microwave above the sink, it is just a strange looking mirror. Also, some people have microwaves and microwave ovens, which is what they gave Principal Franklin.
