What is the Highest Level Possible? (Wii)

I think the highest level is 30. I've noticed that with the monstrous nightmare spine 3 (I think it's spine 3 I haven't played in a while.) fire will sometimes come out of the holes in the back at level 20 or so. Also when you get to around level 20 or higher there is a chance your dragon will roar in the beginning of a boss battle like the boss dragons do. Higher levels increase the chances of special victory animations as well, but even then I don't think there's really any guarantee. To level up after you finish all the training things there's a trick with the challenges in the wild zone. For example, with loop racing in novice difficulty you get the bronze medal with 2 points, the silver with 3, and the gold with 4. The trick is not to go for the gold medal right off the bat. First just get to where you'll earn the bronze, but stop after that. Then play again and stop once you get enough for the silver. Then repeat again and stop once you get the gold. The reason is that if you earn the gold medal immediately it won't give you the xp for silver and bronze, and you can't win them after the gold one is won. Plus it only gives it to you once (unless there's a new highscore possibly though I'm not sure). Use this method with all the challenges on all difficulties and you should be able to reach level 30. I'll look into customization animations for future people and post the info somewhere since no one has really made a guide for this game. I've completed it so many times when I was younger. I still play it every once in a while for old times sake even today.
