It's full of wonder...and magical goodness...
Checked your other stuff, and this is your best work thus far. I've watched this over countless times and it still makes me smile. Siriously, wonderfull characterization and off the wall random humour. I've noticed some don't like this flash due to the annoying blue and red unicorn, but such is the price to pay for creating perposfully annoying characters. At least we have Charlie to sympathise with.
The style is something all on it's own as well. The kinda "carboard cutout" characters reflect perfectly the "eerily too good to be true" happy world you created. And of course, the happyness is just a a put up....cause they steal his kidney.... But I think it's the song near the end that really pushed this cartoon from being a good flash to a great flash. I've hear the tune before somewhere. Care to reveal what it might be? It's driving me nuts.
Again, in conclusion, great flash, but I can see why easily irritated fellows may not agree with this one. However, I wouldn't mind seeing more adventures involving Charlie. Keep up the unicorn work.
