It was ok!
The animation was good, the song was... eh, it owuld have been better WITHOUT WORDS!
It wasn't really funny at all, I mean it is a cute animation but in no way should be number 1.
I am not a fan of the type's of humor in cartoons from Japan. (That is, if they have any)
Oh yeah,
"OMG that rabbit is a slut!!!"
