It's dinner time at the Garcia-Shapiro's household, and tonight Vivian is cooking Isabella's favorite, tacos. Isabella is desperate to eat, so she grabs a taco, not knowing it's under cooked and she begins to eat it. 2 hours after dinner, her stomach begins making gurgling noises she's never heard before. She decides to deal with it through the night, and by morning, her stomach is feeling the worst it's ever been in her life, so she goes to see Phineas about it. Phineas and Ferb decide to create a device that eliminates any pain whatsoever. That's how Isabella is cured.
