The Bug Zapper is a tool for C3 and DS created by MNB. It zaps any insect classified as pest such as ants, stingers and bees, but not insects classified as bug or critter such as butterflies, grasshoppers, and dragonflies.
It has two modes, stationary and roaming. When stationary, it is yellow, when roaming, it is blue. It will find and eliminate pests while in roaming mode. Click on it to change it from stationary to roaming and back again. You will see yellow and blue stars and hear a zap when pests are eliminated.
