Cheers for Fears

It's Jeremy's birthday and I wanna do something really special to show I care and you guys are good at doing, you know, what you do, and, well, all I have is this scrapbook and I don't wanna blow it so can you help me, huh?

When Candace is stumped about what to get Jeremy for his birthday, she reluctantly asks Phineas and Ferb for their help in creating the ultimate gift. Meanwhile, Doofenshmirtz plans to make fears a reality with his Worst-Fear-Inator, but his plans backfire when he finds himself battling his own fears instead.
