Lovely and whimsical.
So far I've only watched two Pico Day submissions, but personally I like this best.
It started off very whimsical--with music that coalesced very well with the meaning (I liked the music too!--which is why I had some hopes about this).
The comedy style reminds me of Tom and Jerry--censored, soft violence, no gore, no talking but only background music and SFX--and I agree with what Xalyx has said, it brings up a bit of nostalgia of Saturday cartoons.
Along the lines of originality points, although the looks were altered, Pico, Nene, and Darnell were still their own little characters.
