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.

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

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.

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

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

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.

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.

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.

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.

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.

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.

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.

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.

Setting the aspect ratio to 4:3 and replaying the credit segments will display both the Wind Warriors and Fire Flyers thanking the player for purchasing and completing the game.

The game has a game-breaking glitch that triggers a blue screen of death. This glitch occurs whenever a Fatal Lua Runtime error occurs and can be caused in specific scenarios, with two known examples being when two different dialogue pop-ups try to appear at once, and if you grab 100 Fire Flyers at once during the final zone of Chicken Con Carnage.

Completing the game with all the rock and water elementals collected will unlock an alternate ending that involves Zephyr, Nimbus, and the army of Wind Warriors returning to their homeworld.

By earning a gold medal in a handful of levels in the game, a blooper reel showing botched takes of cutscenes throughout the game is unlocked to view during the end credits.

The Xbox 360 and PlayStation 3 ports of the game feature a group of wandering Elvis impersonators in the map High Roller Blowout.

Despite not having a physical model, unused animations for the size 33 tornado exists within the game's files. Since no physical model is present for the size 33 tornado, the only way to properly display the unused animations is by swapping the tornado animations.

The game's cutscenes were animated using Adobe Flash and compressed through Bink Video.
