3-2-1 Penguins! is the second series created by Big Idea.
The show was initially created by Jeff Parker, who thought on the concept of flightless birds. He later had help from Nathan Carlson and Phil Lollar, who previously worked with him on "Adventures in Odyssey".
In total, the show has 26 episodes.
In 2019, Phil Vischer stated in an interview that there are discussions about possibly rebooting the series.

- This show was the first for several things:
- The first to mainly use arms and legs as a feature.
- The first that everyone in the main cast appear in every episode.
- The first to be featured in 16:9 when it was brought back (excluding Jonah, as that series prior didn't become widescreen for the episodes until after the Pirates movie (yet there were some post-Jonah episodes that were made in widescreen that never saw the light of day))
- The first Big Idea series to have its Hungarian dub outsourced to Minimax. Before this, VeggieTales' Hungarian dub was outsourced to RTL Klub.
- For the original episodes, it's rather ambiguous if the adventures the kids had were real or just dreams. What makes this confusing are the Comet Lounge segments, as they show that the adventures are in fact real. Since the show's revival, it states that they are real.
- Some of the original titles that was suggested were "Penguins in Space" and "Jason and the Penguinauts."
- Some of the episode ideas that were never made included Michelle becoming envious of her baby sister, Jason and the Penguins visiting a planet where everyone and everything is lazy, Jason and the Penguins visiting a planet where everyone is able to jump very high except for Jason due to him holding a grudge, and Michelle disobeying a rule which dooms an entire planet. The episodes dealing with envy, laziness, and forgiveness became The Green-Eyed Monster, Lazy Daze, and Oh, Mercy!
- According to Tim Hodge, the concept for the revival was different from the final draft. Originally, the twins were going to be stuck in the Rockhopper when the Metric Magnetic Matter Disperser broke. Cavitus was also the main goal the crew were chasing after as he had the part to repair the Galeezle, so every episode has them trying to get the part. Hence why the twins had a spare bedroom in the ship, and Sol's appearances as the voice of reason, similar to Grandmum (Jason remarked about this in the first episode). They decided to change it more akin to the original videos, as they still wanted Grandmum and the cottage to appear. Though the concepts were still kept in the first and last episodes of the series.
- The show received a TV-PG rating when it was on Hulu, despite the fact that the show is appropriate for all ages and got a TV-Y rating on most other services.
