- Cargo Ship: Jiro and Cheepii, the Cheapies donut mascot.
- Fan-Preferred Couple: TaiseixYuudai (affectionately titled TaiDai in most cases), so much that the artist even talked about their popularity in a Lifestream. A lot of the fanart of Sakana out there is featuring those two.
- Hilarious in Hindsight: This movie. No, really.
- Ho Yay: Oh boy. Due to Taisei having No Sense of Personal Space, he oozes this. One example is his bromantic relationship with Jiro (see there for more)
- Yuudai slowly warming up to Taisei after Taisei enthusiastically tries to become his friend could be seen as this, especially considering how awkward and blushy Yuudai is around him. After the brothers and these two have an excessive drinking night together, Yuudai loses his shirt and has to go home with Taisei's t-shirt on.
