While this stage does not directly come from a Pokémon game, the character models of the first generation Pokémon come from the models in the game Pokémon Stadium. The models for the second generation Pokémon come from Pokémon Stadium 2. The concept of "Poke Floats" was reused in the WiFi chat rooms in Pokémon HeartGold and SoulSilver Versions.
The track that plays on this stage is a medley of the different themes that play when battling against other Pokémon Trainers, Gym Leaders, and wild Pokémon in Pokémon Red and Blue, as can be seen in this video.
Poké Floats is a stage similar to Rainbow Cruise, since both are naturally fixed-camera and scroll. The fighting is on top of giant Pokémon floats (hence the name) which are in a constant cycle. Staying on a certain float too long will cause the player to lose a stock because the float goes behind the blast lines. A caution is that the floats tend to become harder to predict as the loop goes on, until it resets back to the first one.
The Sudowoodo Trophy is unlocked upon unlocking this stage.
 List of floats in order of appearance
After Geodude, the last few Unown clear the screen just before resetting back to Squirtle, and the process starts again.
 Tournament legality
Poké Floats was originally deemed legal as a counterpick; it did not move fast enough to cause an overreliance on movement, and the obstacles were rather easy to predict, though some characters could have trouble recovering or going from float to float. Ultimately, the stage was banned from tournament play, due to the possibility of stage spikes, and some of the floats being too unpredictable in their nature, as seen in this clip.
