In 2002, Disney introduced Teamo Supremo as their initial answer to Cartoon Network's popular Powerpuff Girls. Teamo, however, didn't last, despite the fact that it had a more diverse cast (2 boys, 1 girl) of protagonists. The kids of Teamo Supremo were at least a couple of grades up from the Powerpuffs.
13 years later, Disney acquired P. J. Masks, a CGI series developed in France and England. Like Teamo Supremo, the team consists of two boys & one girl, but the gimmick here is that their pajamas magically convert into their costumes when danger threatens. It's been established that Catboy, Gekko, & Owlette are all 6 years of age, which would mean they're in the first grade. Of course, CN rebooted the Powerpuffs last year, and brought them forward to about the 2nd or 3rd grade, but to an indifferent audience. Y'think maybe that was because of P. J. Masks?
Unlike the Powerpuffs or Teamo Supremo, the kids of P. J. Masks don't answer to adult authority figures, and the vehicles they use are there strictly as product placement to induce parents to buy the toys for their kiddo's. As if a real 6 year old could drive a car or use a hang glider in real life......
Now, you'll have to wait until next year for new episodes, as Disney is cycling the first 52 shorts (26 half-hours in all) ad infinitum until a new batch is ready. Let's take a look at a sample episode:
The first season "finale" aired in February, which tells us there is a great deal of lead time between when the episodes are completed in Europe and brought to Disney Junior/Disney Channel here in the US, as it took roughly 18 months to complete the first season.
