The one on the site is in the wrong key. A quick Finale fix could fix it.
It's in C with key sig of F. Should be in G, using F naturals and Bbs when they occur. First notes in right hand should be G-D-G-A. Left should be D-G etc.
The whole Pokemon section could use a touch up, but since this is more egregiousness than a missing tempo or dynamic mark, figured it should be brought to the attention of the updaters.
