I was fed a strange medicine (I was fed)
Then I saw the sea at Shibuya~!
(Cough cough)

I was cast upon a strange spell (I was cast upon)
Then I was pole-dancing at Takeshita~

The dream I had yesterday
Will I see such fantasy again?!
I want to have some rosy
Heart-throbbing every single day!
(Get Hot! Get Hot!)

I was fed a strange medicine (I was fed)
And transformed into a Super Girl!

chururin-chururira-chururururu
If you say these strange magical words
You'll get this strange medicine

chururin-chururira-chururinpa
If you cast this strange spell
My body... my body... my body...
Gets so hot!

Look! From my cocoon
I turn into a beautiful butterfly
I turn into a beautiful butterfly
And fly away---!

I was fed a strange medicine (I was fed)
And changed to whatever I want to be~! haa~
chururin-chururira Forever ah~

*'Geho-geho' is literally 'cough cough', it's probably in here as word play since it sounds like 'get hot get hot!'
In this case, 'chu' is probably an onomatopoeia for 'smooch', so all the 'chu-churu' and 'chururin' is all nonsense words based on that.
