What anime is this song off?!

This is driving me crazy, I think it might be off Welcome to the NHK, but I'm not sure. I'm aware it's not the original song, but you get the gist...

You were probably thinking of Puru Puru Pururin. As for that one my music recogniser drew up a blank [=

It's PoPiPo by IOSYS (I think; it might be by vocaloid)

The one cardy linked is a Hatsune Miku original. Likeable, it's not by IOSYS it's by Tewi & Reisen.

Yes, it was that. Wow, my memory is usually bad, yet I remembered what I thought it was off, I'm impressed.

Thank you.

Man, just remembered how good Welcome to the NHK was. Never seen anything I can compare to it tbh. Any suggestions anyone?
