Trivia: Wario Land
- Fandom Life Cycle: Along with its related series WarioWare and the other Wario games, probably one of the only series that both sells more than a million copies and yet is still somehow in phase 1 of the list, with it somehow having nothing of an organised fandom. Various people have questioned exactly why this is.
- Marth Debuted in Smash Bros.: Dr. Arewo Stein from the Japan-exclusive Game Boy game For The Frog The Bell Tolls makes several appearances in Wario Land 4.
- Name's the Same: Shake has a level called Mt. Lava Lava.
- Word of Dante: While it's never been mentioned in the games, Famitsu magazine referred to Captain Syrup as "Maple" in a Shake preview, implying that her full name is Maple Syrup.
