In the Great Indoors: An excessive amount of rain leads Phineas and Ferb to build Isabella and her Fireside girls a biosphere that can simulate any environment. The incessant rain also leads Major Monogram to believe Dr. Doofenshmirtz is manipulating weather. Jeremy's desire to have a picnic in the biosphere divides Candace between spending quality time with him and busting her brothers. In Canderemy: Isabella wants alone time with Phineas while Stacy wants girl time with Candace without any mention of Jeremy. Doofenshmirtz' Combine-inator hits Candace and Jeremy, literally joining them at the hip until Phineas can rebuild his Molecular Separator.
