Since this one has a lot of errors, I suppose I should replace it. I'm starting to understand why this person was 'blacklisted' now... (How do you mistake 大丈夫 for 太陽??)

Tanoshii koto ga matteiru to itsudatte tanoshin jaeru!
Kawaii MONo mitsukechatta nan datte hoshi ga cchau!
Mori no naka demo mizu no naka demo
Doko made mo oikakechatte II YO!
Yukute habamu nankan toppa! Karuku nage tobashichau zo!

Tanken usa-chan to issho! Takarabako sagashite!
WAKU WAKU suru you na yume no shima e
Tanken takashi mo issho! Dakara daijoubu sa!
UKI UKI suru you na tabi ni deyou!
DOKI DOKI*

Ureshii koto ga atta hi wa MEGATON kyuu no SUMAIRU de!
Ochikon de iru kimi ni HAPPI- takusan wakete ageru yo!

Mahou no tsue de hito furi suru to usa-chan ga KUMA-chan ni henshin
Kore, tama-chan no KUMA-chan da (T_T) konna no KAWAIku nai

Tanken minna to issho! Takarabako sagashite!
WAKU WAKU suru you na yume no shima e
Tanken itsudatte isshou! Dakara daijoubu sa!
UKI UKI suru you na tabi ni deyou!

So here's my romaji:

Tanoshii koto ga matte iru to itsudatte tanoshinjaeru!
Kawaii mono wo mitsukechatta nandatte hoshi ga cchau!
Mori no naka demo mizu no naka demo
Dokomademo oikakechatte ii yo!
Yukute habamu nankan toppa! Karuku nage tobashichau zo!

Tanken Usachan to issho! Takarabako sagashite!
Wakuwaku suru you na yume no shima e
Tanken Takashi mo issho! Dakara daijoubu sa!
Ukiuki suru you na tabi ni deyou!
Dokidoki

Ureshii koto ga atta hi wa megaton kyuu no sumairu de!
Ochikonde iru kimi ni happii takusan wakete ageru yo!

Mahou no tsue de hito furi suru to Usachan ga Kumachan ni henshin
Kore, Tamachan no Kumachan da (T_T) konna no kawaikunaiii

Tanken minna to issho! Takarabako sagashite!
Wakuwaku suru you na yume no shima e
Tanken itsudatte issho! Dakara daijoubu sa!
Ukiuki suru you na tabi ni deyou!
Dokidoki

Tanken Usachan to issho! Takarabako sagashite!
Wakuwaku suru you na yume no shima e
Tanken Takashi mo issho! Dakara daijoubu sa!
Ukiuki suru you na tabi ni deyou!

Tanken minna to issho! Takarabako sagashite!
