JusticeItEasy said: I don't think she's saying "tummy-tummy" more like stuttering while suffering like, "mister eyes! mister eyes hurt!"
Yukkuris do it a lot, specially with the tummy, they go "tummy! tummy hurts!"
No, she doesn't post #2855 She clearly says 'bon bon itai yo' i.e. "tum-tum hurts".
Zidana's translation is absolutely correct, I'm just saying tum-tum sounds better here, since the whole doubling gimmick doesn't work too well in english.
Not my translation, actually. Pgraphics in the comments for the original translated it as 'tummy hurts,' but I saw the doubling in the text and figured there was a yukkurism in there.
