In the UK and Portugal versions of this episode, when Kevin and Duarte were drawing the third clue, the respective hosts' hands and notebooks were in front of the incorrect backdrop (the yellow and white checkered kitchen floor instead of the wooden floor when he and Blue were adding sounds to the silent movie projector). It also happens when they draw the first clue. This was fixed in the US version.
When Mrs. Pepper says "Steve, we cannot hear a thing!" her mouth briefly doesn't move.
A boom mic is visible when Steve and Blue head into their patio to watch the rain and thunderstorm.
Steve identifies Sidetable Drawer's sound as "the sound of you opening the drawer." He should have said "the sound of you opening yourself," since she is supposed to be herself, not just the drawer.
Blue runs in a backward circle during the Mailtime segment.
When Steve imitates the crybaby, he makes the sound of a one-note trombone. When he imitates the giggling baby, he giggles normally.
In Pistas da Blue's version, when Duarte yells GEEMO, he doesn't know which way Blue went. He went to the right. You can't even see Blue when he says GEEMO.
