Applet

An in-game Applet or Kit is a mini-program that allows you to manage a part of your world in C1 and C2.

Some kits are:
 * the Owner's Kit
 * the Hatchery
 * the Observation Kit
 * the Injector Kit
 * the Health Kit
 * the Science Kit
 * the Advanced Science Kit
 * the Emergency Kit
 * the Breeder's Kit
 * the Performance Kit
 * the Graveyard Kit
 * the Genetics Kit (slightly different because you can open it independently to Creatures, but still a kit)

See the applet category.
