It is a hot day in Danville, so Phineas and Ferb are committed to have the best day ever! They kept thinking all morning about things they could do and in the end they agreed to throw a super cool party at their backyard beach and everyone to be invited...and when I say everyone I mean the guest list includes you too. Yes. You're invited to Phineas's and Ferb's beach party but...only if you pass a test...a fashion test.
