Phineas and Ferb (2007)

S3E16 Mommy Can You Hear Me?

When Candace twists her ankle and is ordered to rest, she becomes restless, desperate to catch her brothers in the act. To help ease her boredom, Phineas and Ferb give her a box filled with various items, but instead of being helpful, it only complicates things. Unbeknownst to her, her antics actually assist her brothers in alerting their cosmonaut buddy about an impending danger. Meanwhile, Perry the Platypus disrupts Dr. Doofenshmirtz as he embarks on his latest Chicken Soup-themed scheme.
