魔理沙「おい。霊夢これはなんだ？」
霊夢「かき氷よ」
魔理沙「い、いや、これってどう見てもチ……」
霊夢「かき氷よ」
魔理沙「いや、ちょっと待てよ」
霊夢「いいから、さっさと決めなさいよ！」
魔理沙「……それじゃ、ブルーハワイで」

Marisa: "Oi, Reimu, what is this?"
Reimu: "It's shaved ice."
Marisa: "N... no, no matter how you look at it, this is Cir--"
Reimu: "It's shaved ice."
Marisa: "H-hey, wait a second!"
Reimu: "Just hurry up and pick one!"
Marisa: "...Well, then, I'll take Blue Hawaii."

I'll have Strawberry!

Taking a crack at it: Coffee, Lemon, Strawberry, Ice Cream? (which seems like a slightly odd shaved ice flavor choice, but it does exist), Lime, ?, Blue Hawaii. Can't figure out what the second to last one could be...?

Not pictured: Shou-colored Cirno (Tiger's blood. Dohohoho.)

Probably "Uji-kintoki", matcha syrup with azuki .
