This cartoon teaches you Kana, which is essentially a Japanese phonetic alphabet. There are only a few syllables here on this cartoon, and I think you can put them together. Some help is available at the bottom.
The woman in the yellow dress says "Wasamada You" the whole time, in different portions. Each symbol represents a different syllable. The random other words in the cartoon are listed in English below in each panel. Can you establish how to write Myoo from this cartoon?
