A '''trap''' (Japanese: トラップ ''
trappu'') is an object that can be obtained and used only in [[the Underground]] of [[Sinnoh]]. All traps, except the [[Digger Drill]], are activated when stepped on and can be buried on the ground to slow down or to stop any trainer from returning another player's flag to their own [[secret base]].
The maximum number of traps allowed to be placed by a player is sixteen. If a player exceeds the sixteen, the oldest laid trap will disappear and become impossible to retrieve. Traps laid by a player usually come in two different colors: light orange, for easier and less expensive traps, and dark red, for difficult and more expensive traps. Message traps, however, come in different pastel colors to indicate which message the trap will send out.
