The Stone Stomper uses two interchangeable names in-game. In the intro cutscene for Carnival Chaos and during the boss fight in Showdown with Omegaton, the name Stone Smasher is used. However, in both the game's manual and the tutorial for the move Stone Stomp in Carnival Chaos, the name Stone Stomper is used.

If the Hex values for Zephyr and the tornado are swapped in the game's data, the in-game camera will automatically resort to a first-person perspective by positioning itself within the near center of the tornado. This is because the camera is tied directly to both Zephyr and the tornado.

Before the Earth was implemented as a level selection screen, levels in Tornado Outbreak were originally displayed on a 2D world map and rendered entirely with Adobe Flash.

A Nintendo DS port of Tornado Outbreak, initially titled Tornado Alley DS, was in development from February to July 29, 2008 in collaboration with WayForward and Warner Bros. Interactive. Although this port was cancelled early on, it would suffer an identity crisis as its assets would be reused for the development of other projects. It first became an unreleased Looney Tunes game called "TAZ: The Disaster Master", before becoming the basis for a Crash Bandicoot prototype called "Crash Landed", until it was finally retooled into another Looney Tunes game that did see a release, Galactic Taz Ball.

An unused exit screen with the label "underconstruction_exit" exists within the game files. When activated in-game, the level will abruptly end and transition to the boss variation of the level's stage.

Unlike its Wii counterpart, characters such as Zephyr, Nimbus, and the Wind Warrior use two separate models in the Xbox 360 and PlayStation 3 ports of the game.

The first model is used during fly-through cinematics while the second one is used in-game. The Wii version only used one model, presumably because of the lack of resources on the Wii's hardware.

Originally, a news van and a storm chaser served the purpose of following the tornado around and alerting the people within area to seek shelter or evacuate from their homes entirely.

Enabling free cam will reveal that a duplicate model of Zephyr is placed in the level's default position, which varies depending on the level.

An unfinished test animation for Zephyr and the Wind Warrior exists within the game files; the animation is named "surf"

Within the Xbox 360 and PlayStation 3's map files, there is a partially unused texture containing an early design for Nimbus.

Originally, instead of controlling a Wind Warrior in co-op mode, the player would have taken control of Nimbus. A partially unused transformation animation (which was re-purposed into a flying transition animation for the final game) and a stunned animation for Nimbus can be found in the game's files.

An unused idle animation for Nimbus exists in the game files. The animation is just called small_idle and has Nimbus' model shrunken down.

When it comes to emulation, the Nintendo Wii port of the game struggles to maintain 30 FPS on a handful of levels due to the large amount of objects being rendered on-screen.

Looking at the right side of the unlockable concept art for Showdown with Omegaton will reveal a gigantic dinosaur hiding in the water. Considering that this level takes place in Tokyo, it is most likely a reference to Godzilla.

The achievement/trophy Green Eggs and.... is a reference to the 1960 Dr. Seuss book, Green Eggs and Ham.

A digital PlayStation 3 and WiiWare port of the game was in development, but was silently canceled. A digital version of the Xbox 360 port of the game, originally announced in June of 2009 as an Xbox Live Arcade title, was released on December 6, 2011.

In most cases, the game's interactive music is comprised of seven different layers. The first layer, being the base melody, second being drums, third being bass, fourth being electric guitar, fifth being strings, sixth being woodwinds and brass instruments, and the seventh and final layer, a choir.

The sunlight in the Xbox 360 port of the game uses an animated shader that creates a mirage effect.

Enabling No-clipping mode in Chicken Con Carnage and heading back to the starting point of the map will reveal an unused spawn point for the L.O.A.D. STARR. Presumably, the level was intended to have two different zones.

An unused audio clip from the level Showdown with Omegaton suggests that Nimbus was originally going to tell Zephyr to pummel Omegaton's gigantic kidneys.
