Arthur Season 1 Episode 1

"Francine's Bad Hair Day"- When Prunella screams about Francine getting the ball, you can see Francine looking at Prunella.

"Francine's Bad Hair Day"- In Francine's dream when Arthur is holding the ball, he has no pupils.

When the teacher hands him his test paper, the paper just says Arthur's name and the rest of the paper is blank!

When Arthur comes out of the girl's bathroom when everyone is staring at him, you can see D.W. and Mrs. Woods(not introduced yet). Why are they there? They don't go to that school.

"Arthur's Eyes"- Muffy is in this episode and he gets his glasses, but in "Arthur and the True Francine" he already has his glasses and she moves in.

In "Arthur's Eyes", Arthur is seen without his glasses for most of the show. They appear to be fairly standard, white circles with black pupils. In later episodes when his glasses come off, they appear as tiny black dots.

In theme song, Arthur is seen walking around a globe of the Earth. Unfortunately, he walks over the Pacific Ocean. A special land mass had to be invented between the Americas and Asia to even out the look of the landmasses.

Editor's reply: It's a theme song animation! Anything can happen in it! Like how could Arthur jump through a brick wall? Theme song, people, theme song!
