Interview with a Platypus/Tip of the Day - S2-E7
Factual error: When they exit the London Eye, it stops. In real life, it does not.
Day of the Living Gelatin!/Elementary, My Dear Stacy - S2-E6
Continuity mistake: In "Day of the Living Gelatin" when you first see the TV in Perry's lair, the letters MM are visible on Monogram's jacket. In the close-up they are gone. (00:04:40)
Invasion of the Ferb Snatcher/Ain't No Kiddie Ride - S2-E28
Character mistake: In 'Ain't No Kiddie Ride' Carl reminds Major Monogram that he has no sense of smell and that he was born without nostrils noting it on his resume. But in 'Brain Dead' when Major Monogram sees Perry wearing a face mask he points out that Carl is also a germaphobe. Carl corrects him saying "It's not the germs sir, it's the garlic smell." He wouldn't be able to smell anything since he has no nostrils. (01:10:00 - 01:35:00)
