The DS version of the game was developed separately from its console counterparts and is a side scrolling adventure. It also offers several features that are not available in the other versions. Several minigames are available to unlock and play, most which are updated versions of arcade games such as "Frogger" and "Space Invaders", the latter which references the aliens Kang and Kodos from the "Simpsons Treehouse of Horror" episodes. A virtual pet is also accessible, called "Pet Homer", which allows players to feed, entertain, and save Homer from threats such as choking and heart attacks.
