Here you go.
My additions in bold.
P.S. I think Smileys hat should glow when he uses a hat power
I like the A + Air attack.
Wait, I have a new idea for the standard B attack. He could do something that absorbs the enemy's power (like Kirby minus swallowing).
The problem with the side taunt that you suggested is that that would be only slightly different then the up taunt.
Any ideas on how Smiley can absorb the power are appreciated.
How about instead of the head juggle, he builds a car that drives off the stage?
P.S. what about the hat glowing idea I mentioned?
