Help with understanding a sentence.
During my audio course I heard the following sentence:

osenbei ha eigode "rice cracker" da to omoimasu.

I don't understand the last part. It might also be that I did not hear it completely correct, but it is very close to this. Does someone know what this sentence means or does someone see that this actually should be another sentence, because as I said: it might be that I did not hear it completely correct.Thank you very much for the answers. The explanations are clear, but I still don't see where "da" is coming from. If the sentence above would be without "da" then I would get it!

Answer

You probably know Japanese sentences often end with だ like "あの人は学生だ","蛙は両生類だ", "おせんべいは英語で rice cracker だ". That is why you need to put だ before the phrase "と思います". e.g. あの人は学生だと思います。蛙は両生類だと思います。おせんべいは英語で rice cracker だと思います。
