* On the North American box art of the game, there is a typographical error whereby the apostrophe is placed between the word ‘Hoodlum’ and the letter ‘s’, making the subtitle seem as if there is only one [[Hoodlum]] rather than a group of them.
* Although this is not a Game Boy Advance version of ''[[Rayman 3: Hoodlum Havoc|Rayman 3]]'' (but rather, a direct sequel), it does mark many ''Rayman 3'' characters' first and only appearance on handheld, many of which were absent from [[Rayman 3 (Game Boy Advance)|the actual Game Boy Advance version of ''Rayman 3'']]. These characters include [[Reflux]], [[Romeo]] (referred to as Doc), and [[
Begonix]] (though there was a level in the Game Boy Advance version of ''Rayman 3'' called [[Swamps of Begonix]] but the character never actually appeared). It is possibly [[André]]'s first appearance in a handheld game, although the [[Black Lum]] swallowed by [[Globox]] in ''Rayman 3'' may be him, simply unnamed and with a smaller role. André does not strictly appear in this game, as he merely possesses Globox.
