Sushi from Mario Party Advance now replaces the Blaarg. Also works with the Blaarg disassembly, the Blaarg boss, and any other sprite using that tilemap. It even comes with "water splash" particles instead of lava bubbles.
The first .bin is meant to be included with the custom palette, and the second can be used with Palette E if the palette is structured like SMW's (SMW, SMW Redrawn, SMW Enhanced...)
Tweak the default sprite or edit the sprite ASM files specified above to make the shark use Palette E if using the custom palette or Palette B if using a normal palette, and the "lava" bubbles use palette B.
Through Discord conversation in #graphics I made you aware that your submissions were lacking the in-game screenshots and verbatim quoted the following Submission Guideline:
Originally posted by Submission Guidelines
Upload all of the necessary screenshots to your submission form as pointed out in the "Files to Include" table. Please don't include screenshots in your submission file (the .zip).
I also explained that it's more important for the user to see that the graphics work for the intended sprite than to see the graphics animating. Seeing how you were approached by a moderator and given the opportunity to fix your submissions beforehand, but in the end you didn't for some reason, and later on submitted more submissions without in-game screenshots, I see no option other than to reject these. Please don't ignore the Submission Guidelines nor any moderator's instruction.
Blargg's lunge frames and the lava splash palette seems to be hardcoded to be palette A and Tweaker isn't able to change them. Your submission didn't take that into account for its contents and the description. You could've, for example, remapped the colors in the .bin to use colors A8 to AF and then included a .pal that overwrites those colors. If you're not doing it already, please test your submissions in-game before submitting to avoid this and other issues.
Note: due to a site error, I wasn't able to make a single rejection log for the five submissions that share the same problem with in-game screenshots.
