Just watch. Groudon has 346 costumes. The lava has 45 costumes. The volcano has 11 costumes. The drawing happens over 293 costumes. The rest of Groudon's actions take up the rest of its costumes. I tested thoroughly for problems, so if you do come across them, I dunno what to tell you. There is a one in five chance for an eruption. Otherwise Groudon will slice with its claw. This took me like 2-3 hours to make. I hope you can enjoy.
