Her mom likes the one in yellow tank top and red skirt. She said Rika looks mature in those dresses.
Rika's favorite is the one where she was eating some kind of dessert (?!). I don't remember a pic like that though.
Just found the file. The only words I caught were "Odeko" and "Kiiro".

Seems like My Japanese hasn't improved since then.
It's "shiratama". She even wrote a song about it.
those are interesting things about rika. thax for the list tama-chan. i thought her and aibon will fight alot more than nono.
You're welcome. There are some on the 1st page as well.
Rika and Aibon did fight a lot when they were in Tanpopo together. Not so much now, I think. Rika's closer to Nono, though, maybe that's why they fight a lot.
