This is the first episode where the title card did not have the full name of the episode. This is likely due to the length of the name. "Birthday Battle: Transmorphers Versus Unicorns" was shortened to "Birthday Battle."
Unlike the previous two episodes (and the subsequent episode The Fair Bears), this episode is unavailable on Nickelodeon OnDemand.
