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]], can be buried on the ground
and be used to slow down or to stop any trainer from returning another player's flag to their own [[secret base]].
When buried on the ground, one can distinguish a trap from a sphere by looking at the color of the sparkling light that one gets to see when the [[Nintendo DS]]'s touch screen gets touched. Traps give out a white sparkling light while [[sphere]]s give out a yellow one.
Players may help each other out of traps by speaking with the trapped. Strangely, this works even for the Alert Traps.
