I am sorry if I come off as overly negative, but this release honestly should have been a development build, not a finished, released mod. You clearly know how to make and import prerendered assets into the game so the fact that there is a complete lack of animations (besides a few assorted single frame animations, which you seem to have poorly ripped from screenshots?) is disappointing as this could have been a lot better than it is. It's easily my least favorite part of the mod and you could have put a lot more effort towards the visuals beyond a single STNDA.
I find the moveset to also be quite lacking. I admittedly haven't ever played Battle for Bikini Bottom before but his toolkit doesn't seem all that "Spongebob-like" which I acknowledge is a subjective opinion, but it leads to a character who, at least to me, is not that engaging to play as. (I also question the necessity to have a run button when you could have either given him regular acceleration or built his moveset around a slower movement speed).
His listed moveset is also a bit misleading as despite it stating that you need to hold the spin button for the ground pound, you only tap it once to be frozen in midair with no way to cancel out as he performs the slam. You also can't do the ground pound if you double jump, which isn't mentioned anywhere as far as I can tell. Aside from that, he basically just plays as Amy but with a better jump and a ground pound instead of midair hammer swing.
Overall, while it is technically competently coded and functions as intended this mod is a disappointing experience that I feel was put out way earlier than it should have. I'm leaving this review not to put you down or discourage you from making more mods, but rather so you can take the constructive criticism and learn for your future projects.
sorry for disappointing you with this…
