Olympia and Otis, along with 18 other agents (past and present) compete in a very special O Games. Will Odd Todd be able to defeat all the other contestants and shut down Odd Squad? This fanfic is partially based on Battle For Dream Island.

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.
