Manhole

Overview
Manhole is a league 6 trap which when stepped on from any direction will create noise vertically.

Strategy
This trap can be used to alert your Guard Doges from above or below. It will cause the player to move away from the manhole, potentially into other traps. Using it with traps like Empty Can will make the manhole much more useful, as the manhole will alert any potential doges from above and below and the empty can will alert the sides. When encountering it move horizontally after waiting a bit to see if there are any doges.

Manhole is outclassed by bucket most of the time, as bucket costs 3 bars just like Manhole and creates vertical + horizontal noise. However Manhole has more reach, so depending on your strategy Manhole can be better.

Trivia

 * This trap is a reference to Jackie Peng, an enemy in The Battle Cats, another game developed by PONOS.
