Bunnies are the characters the player controls, although the term "Bunny" is generally used to refer to players who are not in control of Robosaru.
Bunnies have three item slots: mouth, back, and side. Items that are in the mouth can be dropped with Right Click or used/placed with Left Click. Pressing Q or E rotates the items that are in these slots.
Bunnies without a collar earn 2¢ every 2 seconds. Bunnies with a collar earn 6¢ every 2 seconds. Bunnies inside the Dropship earn 1¢ every two seconds, regardless of whether they own a collar. Robosaru earns 20¢ every two seconds.
