Odd Squad is a government organization run exclusively by kids that seeks to put an end to everything odd. One day, a portal connecting Equestria and the large population of Toronto appears out of nowhere, and it won't disappear. When six ponies make their way to Toronto at Princess Celestia's request, they must find out what this "Odd Squad" is, unaware that there is one odd-stricken villain trying to hunt them down.

Based on the idea that "Odd Squad and MLP really do go well together, don't they?"

Partly inspired by these two joke tweets from Odd Squad's co-creator about Odd Squad crossing over with MLP. Missed opportunity.

Takes place during Season 1 of Odd Squad and during Season 5 of MLP: FiM. Villains debuting in Season 2 of Odd Squad are added for the sake of the story.
