Just for the record I want to leave a few notes regarding the episode order I choose for this TV show. After some research I didn't find original air dates. Earliest reference comes from English wikipedia which mention 2004-01-05 as the first air date. However on the wikipedia there isn't specified any episode order, so I choose the earliest comprehensive episode order I found on fernsehserien.de. In particular I used "Deutsche Erstausstrahlung: Disney Channel" according to which the first episode is "A Friend for Dragon" from 2004-09-15.

If anyone find better source for original air dates, feel free post it here and update my episode order.
