In terms of the Carmen Sandiego show on netflix, this takes place around season 2. If anyone has never watched the new Carmen Sandiego series, you can find it on Netflix. And I would highly recommend you do. Otherwise you won't be able to understand a lot that's going to go down in regards to that series

This takes place after the group vacations on the yacht but before the events of the epilogue play out

The girls only hope to face the trio of sirens and their ally is in the form of four mutant turtles, their master, and their two human friends. MLP/Ninja Turtles crossover.

Inspired from a fan video.

Takes place during the events of season 8 and will eventually lead up to the finale. If you're not caught up in all the current events in season 8 I would suggest you do so because there will be spoilers.
