- Memetic Mutation: One of the most well-known memes in the series is an image macro consists of both Heidi pushing Clara on her wheelchair, with the next image consisting of the photoshopped image of Heidi killing Clara by shoving her down the cliff. The image macros usually go with joke captions of either Heidi disagreeing with Clara's opinions and killing her for them, or Clara making very dumb jokes and Heidi killing her for that too.
- Moe: Heidi.
- Signature Scene: As written above, the 43rd episode has a well-known scene of Heidi bringing the disabled Clara to watch the scenery from the mountains.

- Tear Jerker: Poor Heidi's progressive fall into despair as she's away from home.
