For my end goal, I just wanted them to be used basically the same way as in the original game.

I've never played Plants Vs. Zombies, but I'd imagine they have at least an idle animation, attack animation, and maybe a death animation.

Again, I'd recommend picking just one character and giving it all the animations you think it would need. Once everything is polished to your liking, try submitting that.
