Thanks for all your awesome questions for our Comic-Con panel everyone! The press conference had not only the cast of Phineas and Ferb but also the creators of Fishhooks and Gravity Falls.
On the Phineas and Ferb side, we got an official confirmation of the upcoming Marvel x Phineas and Ferb crossover episode from the voice of Phineas himself, Vincent Martella. Both Alyson Stoner, the voice of Isabella, and Vincent Martella were incredibly excited by the fact that there's a huge Phineas and Ferb wiki behind them supporting the show and the characters.
Here's a video of the panel from Comic-Con panel for Phineas and Ferb!
