Why do the purple shields have horns to the side? Because in Skyward Sword they don't have those.
He was using MC base sprite of the Mirror Shield for them. I've been studying what bases he's been using for a lot of these. I have no life, so I occupy my time with meaningless crap like staring at sprites for over 3 hours. Out of shear boredom. Complete. And utter. Boredom. No life!! So Sad!!
To Miles: I've noticed you haven't added the golden insects in from TP. Been wanting to say something, but didn't know how to put it into proper words with everything I wanted to say (which is a lot). Well anyway, I think I can understand why, as you'd have to make the bases for most of them. Actually the only one you wouldn't have to make a base for is the Butterfly as the Minish Cap has the Joy Butterfly.
Of course Skyward Sword also has bugs to catch. Though this time the Hornet would also have a base since you could use the bee for said base.
Here's the figurine form of the Joy Butterfly.

And the joy butterfly itself
Google was being stupid and wouldn't let me find the sprite sheet for the Butterfly. I'll keep searching though. I only looked for about 2 minutes anyway. Wanted to get this posted quickly.
