The Lion King 1 1/2 for Game Boy Advance was released in European territories not as as the movie's European title The Lion King 3, but rather simply The Lion King, with a large image of cub Simba added to the box art, despite not being playable in-game. The blurb does specify that the game is based on The Lion King 3 and alludes towards only Timon and Pumbaa being playable however.

The original US box art could also be considered misleading to a much lesser degree. While being open about what movie it is an adaptation of and having a giant Timon and Pumbaa ripping through the paper at the top, it uses a modified version of the first film's promo art, featuring Mufasa's spirit head, with cub Simba also present in silhouette (albeit significantly smaller relative to Timon and Pumbaa than on the European box art). This imagery that was not used to market The Lion King 1 1/2 anywhere else. Both boxes' blurbs also feature a screenshot where Simba, as an NPC, is in the center.
