"The Happy when you know it" rip off... This explains China copys everything. Especially the Chinese PS Vita.
You know every first-world language has their own variation of this song... right? I mean I'm sure you could pull up a recent American children's show with another variation of this same song and call it a "rip off." Nobody owns its copyright and it's likely the original song wasn't even in English. And how would something like this explain anything?
