* HeAlsoDid: If those commercials and Toof’s origin film look familiar to you, it’s because they were animated by Dan Paladin, the person who would go on to create ''VideoGame/AlienHominid'' and ''VideoGame/CastleCrashers''.
* KeepCirculatingTheTapes: The game has yet to see any sort of re-release, despite being one of the first games to support Xbox Live. This is possibly the reason why it was never re-released.
** The game is backward compatible on the Xbox 360; however, as of 2010, Xbox Live for the original Xbox was discontinued, ending support for online play of all Xbox titles, including ''Whacked!''.
* SavedFromDevelopmentHell: The idea for the game was conceived in the mid-90's before Microsoft finally greenlit it for the Xbox.
* WhatCouldHaveBeen: The original concept had a lighter and cartoonier tone similar to ''WesternAnimation/LooneyTunes'' [[https://www.youtube.com/playlist?list=PLZzi5C0ZMTHt40BRlbkR4UjDuDX7pmHvN with the music reflecting it]], But over time, the game's tone shifted to the darker and edgier tone to appeal to an older and wider audience.
** The character that became Eugene went through the most changes because the team found Envy to be the hardest sin to create a likable character for. The early concept art shows [[http://www.jeffcarlisle.com/node/391 a green elderly lady named Evil Spinster]], and [[http://www.jeffcarlisle.com/node/392 another is a]] [[GreenEyedMonster literal green-eyed monster]] with disproportionate features, [[https://www.facebook.com/SaundersCreative/photos/a.1515911705184083/1515911841850736/?type=3&theater and this one shows a midget basketball player with long robotic legs]].
** Presto Studios considered making two spin-offs titled "Whacked Kart" and "Toof's Big Day", but ''Whacked!'' didn't prove to be licensable enough.
* WorkingTitle: "Boing" in its lighter and cartoonier stage, and "Big Toe" when it was first conceived.
