But sometimes I'm afraid that it'll not be like what I've hope for. Like I haven't seen Perry talk yet. And they'll all forget Perry's secret identity, being more-and-less useless for the timeline. This did caught my attention, though.
Here's where the mystery figure came from:
EDIT #1: This.
It's a glimpse of Perry's background story/history. It's interesting, though it might contradict my "Perry is Phineas and Candace's Father" theory. Let's see some more. And I'm seriously curious about the mysterious figure from the trailer! I totally can't wait!
EDIT #2: I have watched the movie! Yup, there were some up and downs. First, well, Perry was awesome along with Alternate Candace a.k.a. Candace-2. Especially Candace-2! She's like a talking Perry the Platypus! You know, the one who cares about Phineas and Ferb so much while kicking the butts of their enemies.
The ending... was cliché. Yep, mind-erased. Hello... it's so common in plots where they know something they shouldn't know. And the mystery figure's a shrub. Go figure. And there's no Perry speaking either. Even Platyborg! Yup, that was disappointing indeed.
