Episode Summary
Maddie and Olivia are walking in town. All of a sudden, a mysterious figure takes Olivia. She shrieks for help. Maddie knows she has to do something about this. She runs past Doofenshmirtz Evil Incorporated, where Doof is gathering some gear to go mountain climbing. He's surprised Perry hasn't showed up yet. He shrugs, gathers his things, and leaves for his quest. Meanwhile, Phineas and Ferb are working on something big. They're devising a system for remembering everything! Phineas knew he would remember to do that. Baljeet saw what he did there. Buford thinks it's because of that extended title sequence. Irving seriously thinks Buford should go to summer school. Baljeet doesn't want him to for obvious reasons. With Maddie, the mysterious figure has taken Olivia to the top of a mountain. She spots Doof, not knowing it's him, and asks if she could tag along. Doof says no after what she's done to him. She asks what she did. He recaps to the first time she defeated his creation, and the time she destroyed his hypnotizing gun. Maddie doesn't remember any of that. She forgets him and Doof continues on his own. He's hoping to find pizzazium infinionite. Maddie is hoping to save Olivia. She climbs up the mountain, which takes a while.
