Stop and Go Barrel

From the Super Mario Wiki
A Stop and Go Barrel.

A Stop and Go Barrel is a type of barrel that appears in the Super Nintendo Entertainment System game, Donkey Kong Country. It appears as a dark barrel with either the word "Stop" or "Go" on it.

This type of barrel only appears in the level, Stop & Go Station. During this level, there are many Rock Kroc enemies dashing across the areas, and they can easily hurt the Kongs. Numerous Stop and Go Barrels are placed throughout this stage, showing the word "Go" on them. If the barrel is hit, it turns into a Stop Barrel for a short period of time. While it is a Stop Barrel, all the Rock Krocs in the area cease to move and curl up into a ball, becoming harmless. After a short time, all Stop Barrels become Go Barrels again and the Rock Krocs will resume moving.

Noticeably, when these barrels are set on the "Go" setting, the lights illuminating the level turn green. When they are put on "Stop," the lights turn red.
