I can´t figure out the password hint to this file: https://bowlroll.net/file/162361
The hint can be found here: http://www.nicovideo.jp/watch/sm32958751
It reads: "( 言ω言)がよくつくる食べ物カタカナ四文字 ＋ 動画の番号（sm抜き）"
The second part is pretty clear, just the video number without the sm in fron of it, so: 32958751
But the first part if translated, says "Four foods katakana four letters". Does that mean four food items in katakana with each of them being 4 letters long? Which food items, in which order?
Can somebody please help?
