Sentry Bug

The Sentry Bug is an enemy that appears in Sonic Mania. It is a mass-produced Badnik model created by Dr. Eggman.

Appearance
The Sentry Bug has a butterfly-like, dark green body. It has a yellow seam running down the middle of its abdomen with black square-like designs along the side of its body. It also has two yellow spikes at either side of its head and with what appears to be a red spike running down its back. It has two propellers to give it the ability of flight.

Overview
The Sentry Bug appears in both acts of Titanic Monarch Zone. Once it locates its target, it will send out explosives that follow the player. It will create a polygonal laser grid that will continue to follow the player for a few seconds. Afterwards, the explosives will detonate.

A simple Spin Attack will be enough to defeat this Badnik. Upon their destruction, they release an Animal. Destroying the Badnik will also deactivate its explosives.
