Omar has great plans to surprise Orla with a 500th birthday party. But due to some intense Odd Squad history, normal party gifts aren't going to fare well with her. So, while Opal keeps Orla busy with a string of false villain leads, Oswald and Omar must track down the ideal birthday presents.

While solving oddness on a farm, the team meets a kid named Jeremy, who is their biggest fan. Opal really wants to shine in front of him, but the team accidentally gets locked out of their van. While half of the Mobile Unit distracts Jeremy, the other half tries to answer the van's security questions using math in order to get back inside.
