Trivia

 * Despite being a third Grader, Otis has been seen hanging out with fourth Graders more then other third Graders. He is mostly seen with Brian.
 * Otis was seen at the Children's Hospital Boston along with his mother in the Arthur's Guide to Children's Hospital Boston website feature, wearing a red sweater over a white shirt, and brown pants.
 * In the intro for the show, Otis is seen along with Alex and three other unnamed fourth graders (4th Grade Male Aardvark, Brian, and 4th Grade Male Rabbit) and the rest of the main characters. There is a chance Otis, Alex, and those three fourth graders were suppose to play some role in the series earlier on, but it either never materialized or may possibly happen in future episodes and seasons.
