Just go into the Frames sprite then go to costumes, take your madness oc and try to copy the grunt's movements, you can even copy directly over it if you want, I don't really care lol, after you're done animating, make sure to delete the grunt. Your results may differ from mine, but that's ok, remember, practice makes perfect! You can change the background and music to your liking. (credit whoever made the sprites for your oc please)
Demott for the sprites should be very simple and easy, only 30 frames 5 by 5 by lykia
