Ha, you thought I was dead? Joke's on you, I've only been dead on the inside!

Unfortunately, none of these enemies (Except the Freezie-Boo, Watoboo, Poiso-Boo and Invisiboo) look very appealing to me, this could definitely use work because of these reasons:
1. Co-Cosapain is just a simple recolor from Yoshi's island. The tree is also a recolor from SMB3. And I believe the coconut looks like the sphere on the goal pole from SMB1.
2. Small Fry is a simple recolor from SMAS SMB3's Firesnake sprite.
3. Broozer looks too small. I'd make him have 32x32 pixels than 16x16. However the punching style looks really good, but the squishing sprites are poorly made from the first two (And I mean it with how the top of his head just has a curve). Flattening broozer (Polishing the sprites are recommended) is a good idea for this. When broozer punches I would make him turn more as he goes.
4. "I'm Lazy"
That honestly doesn't mean that you can just leave the kritter sprites like that and post it. If you're going to include "Kritter" sprites in this I would at least put more effort and make it look good (The sunglasses are facing too forward, Legs can be bent a little more to the front and the arm behind it's chest could be pushed a bit behind). If you're lazy you can come back to it when you think it's time and add what is too complicated to do after the sheet is posted, you can try again, but what is the point of leaving sprites lazy if it is going to result in people not using them?
5. I would say that the nabbit sprites are slightly improved over your last one, but the big issue with these now is these are shorter. Previously you made nabbit taller and now it's smaller, or is it not a regular nabbit... small nabbit? If you were trying to make normal nabbit then these need to be taller. In SMM SMW style most enemies that are Bowser Jr's size are limited to 32x32 pixels. Try imitating nabbit to that size and see how it goes. Since it is the only enemy in this sheet that just says bonus above it I cannot tell if you're going for a small variant of nabbit or a regular nabbit.

The recolor Lava bubble and Boos sprites are good but everything else needs work. Next time I would avoid posting lazy sprites and try again when you need too.

I would say that my theory is that of how much users comment in a sprite sheet usually appears to be based on users interest and/or quality of the art. I just had to clarify it. These sprites seem to lack the style, here's why:

1. Their noses are missing, are you sure that's right? I would depict them in.

2. I feel like topper is too tall and might need to be shortened a bit (About 5 to 9 pixels shortened would do the trick).

3. They all break the 3 Color rule, Rango has more colors than all the other broodals. You might of intended to make the black parts part of the background like bowser but if you did, Hariet's helmet would blend in a lot, including the spike balls that are just below it, and her boots.

4. Topper and spewart's hands are just circles, while making it detailed would be nice. Hariet's gloves should be detailed as well. A suggestion for this would be making fingers into the circled hands.

5. All four broodals are missing teeth. Bunnies have teeth and these could use some.

6. I would make spewart lean to the front when spitting goo, currently the sprite here has him standing, which is odd.

7. I'll point out that the hats are too small when it is thrown. Especially hariet's helmet doesn't look spiky enough, since it just has white dots which make it look more like metal beads on the front of the hat. What I mean with the hats being small is the fact that it would be quite hard for the player to stomp on it because it is not wide enough, you should probably use the SMM SMB1 Bowser. Jr's shell as a reference.

Isn't this like the third time you said this? (+1 download)

Please, ... I think we had enough, the comments aren't for requesting especially you posting another one. I recommend you, to stop immediately before this comes to a final. And you could always give it a shot, you know?

I especially like the gold, nice looking bills. The only complaint I have is not with your work, but the checked backgrounds make ripping these sheets for games an absolute nightmare.

Why are all the bullets named Bill? I want a Bullet Jerry.

That's odd, I could've sworn that Misteryt1MFGG originally made an NES Wario sprite. Seems like he didn't.

Nice recolor/edit nonetheless.
