As the only playable character is Keroro, instead of switching between characters, you switch between Kero Abilites. Each Kero Ability has a different play style, and some allow Keroro to use Allies to help him in battle.
|Knight Keroro||This Kero Ability gives Keroro a sword to attack and a shield to defend.|
|Boxer Keroro||Boxer Keroro uses boxing techniques he saw on TV to punch opponents with swiftness.|
There are many kingdoms which Keroro can go to in order to conquer and put them in the Anti-Tororo Alliance. There is also the Tororo Kingdom, the kingdom that Tororo rules with a iron fist.
The first kingdom of the game, which is very peaceful. It acts as a tutorial kingdom, and has very basic enemies from both the Sundial Army and Bowser's Castle.
A floral sewer under the Mushroom Kingdom and Inaba. It is ruled by a democracy of Piranha Plants and other floral enemies. Keroro finds the Warp Stone here, which allows him to warp to any Kingdom he has been to.
