This is the last episode of Season 1 of Blue's Room.
This also marks the final time the Season 1 structure of "Blue's Room" was used, as after this episode, many changes were made to the show's episode structure.
Due to this, this marks the final time "Polka Dots' Puzzles" is played, as it was removed altogether starting with the next episode.
This is the final episode in which Peter Linz performs Polka Dots and Doodle Board. Starting with the next episode and Shape Detectives, both characters get new performers. However, the name of these performers is currently unknown, as the end credits, nor Nickelodeon, don't list who puppeteers who on the show.
