Now that I've actually listened to the full version of Hareyaka Sokuyaka Pikarinrin, a song which I originally didn't really care for, like a lot of current HaroHapi GaruPa exclusives (Which I just now realized are only Hyper Smile Power and Smile Bouquet...), because I simply haven't listened to them enough, I must admit that it's incredibly cute! It's like Yumeiro Sandwich, but a bit more upbeat, which I definitely buy.
