Agent Onyx, a new agent at Odd Squad, gets a strange condiSHAWN that turns her into various object versions of herself. It's up to Otis, Olympia, and Oona to save the day when Onyx turns into a paintbrush version of herself. This is listed as a crossover because object show characters are somewhat involved (as Onyx's odd diseases). Prequel to an upcoming Odd Squad fanfic.
