Stages in Toshiko Crash-Up all have a crossover/fusion element in which two or more series under the Toshiko brand come together to make a new stage with new hazards. Stages may also have these hazards turned off. There are 20 stages in total, all of them available from the start.
- \V/ and Kaiju Karnage!!! are the only franchises to only be represented in one stage.
- Mt. Sanskrit is the only stage that ascends. Mineshaft is the only stage that scrolls horizontally.
- Mt. Sanskrit, Floating, Cojjhev, and Obalon HQ are the only stages with pitfall hazards.
- Floating and Cojjhev are the only primary stages that do not have a character who represents their franchises.
- Bipolar Express, West Wing, Stormrock City, and Zoo are the only stages whose secondary franchises do not have a character representation.
