I believe there should be an official Bluey potty training episode. From what I've learned, motivation is key in helping aid in this milestone. Bluey is a likeable character (as well as the titular character!). In this day and age, I believe a potty training motivator like Bluey, as well as her family and friends, would really work, especially as many children are growing and learning alongside each episode. 

Pampers already has Bluey themed "Easy Ups" prints, as well as fun games to use whilst potty training such as "Bingo's Potty Bingo". With an episode, it would be easy to model just how the potty process works, as well as tie in a bit of the collaboration! Also seeing as book versions of Bluey episodes are available, reading the story version of a potty training episode would be much help if parents or caregivers didn't have access to the show at hand. This also gives them a chance to read to their children, helping them to reinforce the skills, or if television use isn't that big in the moment.

All in all, I heavily believe that an official potty training episode WOULD WORK! Many roleplaying, toy channels on YouTube create videos using Bluey toys with the themes of going to the bathroom and washing up, but not many like the idea of "unofficial" videos. I know this from experience, YouTube content sometimes isn't the best. 

Thank you for reading. I would love to help out many, especially during a bug milestone like this.
