| Spoiler warning!|
This article contains plot details about an upcoming episode.
This page lists the episodes that have not aired in the United States through Nick Jr. yet. Since Nick Jr. is considered the primary source for this animated series, these episodes are considered unaired regardless if they have already been shown on another country's own network.
Once an episode has officially aired in the US, it will be removed from the list.
- Some of the unaired episodes have already aired outside the United States.
