If you do keep the penguin, it absolutely has to come later, after the explosion thing has been established, otherwise it kind of ruins it and doesn't work. After watching it all, I think it may actually work if it comes close to the end.
Pacing wise...I like it. A lot. There's a slight slowdown in the middle with a bunch of long clips but that's all. The one thing though is that it seems like almost all my Sailor Moon ones are in the last like 15 minutes. Those should probably be split up a bit.
The jigglypuff one I still think is SUPER funny but still has an audio issue at the end.
Not sure about the jelly doughnut one. I may be missing the joke or something but it just seems sorta...there.
Love the whip my hair back and forth

The FMA one I just hope doesn't get red flagged lol. I mean, by all rights it's PG 13 I'm just paranoid from last year's drama.
I'm torn on the library one. It's SUPER adorable but towards I was ready for it to end long before it actually did.
Nice adding in the explosion noise to the Robot Unicorn one, but I think I'm still gonna fix it up a bit and make it a touch faster/bigger.
I love the hamster fluffy. It's so cute.
The Pinky and the Brain one made me for real laugh out loud.
I still feel like the screw in the tuna one could be shorter, but it's definitely much better now.
Knife wrench XD
Dunno how I feel about the Who's on stage one. It also just feels sort of...there. It may be different if like, it was at a concert type venue of some kind?
Watching that Excel Saga one I was thinking, since there's an explosion and fire thing in it, maybe it'd be better with having the explosion noise in it.
The Touch Me one still has that small audio glitch in it and just needs a couple seconds cut off (or I could fix it while I'm doing stuff tomorrow)
The fluffy exploding Full Metal Alchemist one is brilliant.
Upon watching it all...placed where it is I think I re-love my Princess and the Frog one. lol.
Also my production tag isn't in the credits. =p
