アナタが落としたこの箱を 自慢の工具で開けてみた
輝く瞳に映るのは まさに進化の宝石箱
「これはモノ凄い発見であります
平成は本日より河童元年であります！」
|kan2=
何千年もかけてできた 人間の歴史の集大成
小さな小さなこのハコに いったい何が詰まってるの?
|kan3=
山にはこんな凄いもの売っていないし
やっぱり人間の世界は 凄く面白そう！
|kan4=
バラして直して光学迷彩 光の世界へワープしてみたい
だけどあたし 河童だから この山からも出られません
小さなボディで無限の能力 なんかあたしに似てる気がするのよ
だけどあたし 河童だから お値段なんて付けられません
|kan5=
そのうちあなたがやってきて　このハコを返せと言うのかな
もしそうなったら寂しいな まだまだ調べてみたいのに
|kan6=
こんな凄いもの作れたら 楽しいだろうな
苦手な時もあるけど やっぱり人間が好き
|kan7=
１人で解けない謎があるのなら　あなたと二人で解明したいの
全てのコト　興味あるわ　だけどとりあえずキュウリ
バラして直して光学迷彩　アームを伸ばしてフラッシュフラッド
だけどあたし　河童だから　水没にはよく気をつけます
|kan8=
「こんな面白そうなモノ見つけちゃったんだもん
このハコだけは　絶対に譲れないんだから～」
|kan9=
夢見た世界とリンクする　魔法の力で
もっともっと仲良くなれそうな　予感がしています
|kan10=
１人で解けない謎があるのなら　あなたと二人で解明したいの
だけどあたし　河童だから　もちろんコーラもキュウリ味
（あいすきゅ～かんばぁ～！！）
バラして直して光学迷彩　あなたと二人で解明できたら
こんなあたし　河童だけど　これからももっと宜しくね
そんなあたし　実に河童　時々遊んでね　かっぱー

This box that you've dropped
With my proud tools, I tried to open it
What's reflected in my glittering eyes is,
Certainly, a chest of evolution
"This is a very great discovery!
Today, the [[Wikipedia:Heisei period|Heisei Period]] ends and the first year of the Kappa Period begins!"{{ref|gannen}}
|eng2=
Spending thousands of years
Compiling the human's history
It's so tiny, in this little box,
What on Earth could be stuffed inside? 
|eng3=
At the mountain such amazing things can't be bought
Besides, as I thought, the human's world is
Wonderfully amusing! 
|eng4=
Take apart, put together, optical camouflage
It's like the light of the world warps around it
However, I'm a kappa, therefore
From this mountain, I never leave
In this tiny body are infinite abilities or something
I get the feeling that I'm still the same, though
However, I'm a kappa, therefore
You can't put something like a price on it 
|eng5=
You will turn up someday
Saying things like "Bring me back that box"
If it happens, I'll be lonely,
Since I want to examine it on again and again 
|eng6=
If I could make such an amazing thing
That would be fun, I suppose
My weakness comes again, however
As expected, I like humans 
|eng7=
If there's a puzzle that I can't solve alone
Together with you, we can unravel it
I'm interested in everything
But, it starts with cucumber
Take apart, put together, optical camoflage
Extend arm, flash flood
However, I'm a kappa, therefore
I'll try to be so careful not to submerge anything 
|eng8=
(Since I discovered such an amusing thing,
There's no way I'll let you only have this box) 
|eng9=
I dreamed that I linked with the world
With a magical power
More and more, becoming used to making friends
It's a premonition 
|eng10=
If there's a puzzle that I can't solve alone
Together with you, we can unravel it
However, I'm a kappa, therefore
Of course the cola is cucumber flavor {{ref|cola}}
(Ice Cucumber!!)
Take apart, put together, optical camouflage
I'd like to unravel it together with you
As I'm such a kappa, however
From now on, treat me better, too, OK?
I'm like that, I'm truly such a kappa
Please play with me just sometimes, OK? Kappa~
|notes=
{{note|gannen}} This is a parody of a line from [[Wikipedia:Sgt. Frog|''Keroro Gunsou'']]'s "Kero! tto March": ''Today, the Heisei Period ends and the first year of the Keroro Period begins!'' ({{lang|ja|平成は本日よりケロロ元年であります}}, Heisei wa honjitsu yori Keroro Gannen de arimasu). Keroro also appears there probably because he also loves human works and/or otaku goods.<br/>
{{note|cola}} This joke is based on the odd cola "Pepsi Ice Cucumber", which was sold (possibly only) in Japan. When Touhou fans encountered the bizzare idea of a collaboration between cola & cucumber, they found such weirdness suited to Nitori's very human-friendly, un-youkai-like character. This meme was then used very frequently for a while.
