Once the gang fights Azula, they realize they left the portal open and Azula steps though. But Phineas and Ferb force her back in once they realize she can't firebend because bending doesn't exist in their show. Meanwhile, Doofenshirtiz has also gone to that world to Platypus-bearnapp all the platypus-bears. So Perry and Bosco team up and beat up Doofenshiritiz up to the point where he loses his memory. After that The boys say their goodbyes and go back to their show.
