Season 2 and Season 3 were originally formatted as a single 52-episode season. However, for unknown reasons, Cartoon Network re-labelled the second half of the second season as Season 3 and then split the original third season into Season 4 and Season 5.
Season 3 effectively has 25 episodes. This is due to all of the digital shorts being counted as a whole episode, and the double-length episode "Bismuth" being counted as two separate episodes.
Season 3 took the shortest amount of time to air, only airing within the span of three months.
