Sometimes, the Alphablocks/Numberblocks break the fourth wall (addressing, mentioning, or appearing to observe viewers on the "other side" of the TV screen). This article lists all known "fourth wall breaks" in the Learningblocks series.
- Alphablocks: C cracks the screen (a literal "fourth wall"). N tries to stop the transition when the camera goes to O. O gets curious and looks at the viewers with his magnifying glass.
- Top: When I is going to say what happened to T after O says what happened with T, E stares at the screen unhappily, because O was the first one to get the answer, not I.
