User blog comment:Black Spiderman/Phineas and Ferb: Across The Second Dimension/@comment-1758246-20100304090446

I'm wondering what the subplots are gonna be. If my theory is correct, and they use the other-dimension Perry, then Perry will end up fighting Doof as usual. Candace's plot would probably have her tag along with her bros somehow and try to bust them in some way, or she'll just stay home and wonder where Phineas and Ferb are. I suppose the other kids would probably end up tagging along for some reason. Then, for sure, there is gonna be the Phineas and Ferb of the other dimension. I wonder what they'll have to do with the plot. What I'm most interested is this "eviler" Doofenshmirtz. I bet he'll have a goatee.
