traps in the Mystery Dungeon series|Dungeon tiles#Traps}}
A '''trap''' (Japanese: '''トラップ''' ''trap'') 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]] .
Traps can be bought by the player using [[Sphere]]s or be found placed in the ground. 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 to escape and less expensive traps, and dark red, for more difficult to escape and more expensive traps. Message traps, however, come in different pastel colors to indicate which message the trap will send out. This helps the player as to not get caught in her/his own traps.

It should be noted that a laid trap does not differentiate between the player that set it from any other player, so care should be taken to avoid accidentally stepping in it afterwards.
When buried on the ground by a different player or a computer, one can distinguish a trap from a sphere by looking at the color of the sparkling light. As the [[Nintendo DS]]'s touch screen is touched, nearby traps will 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.
Some traps also come in furniture versions that can be placed in one's Secret Base. These traps are visible to everyone, but have the same effects as their Trap counterparts when stepped on.
==List of traps by function==
Alert traps send messages to everyone in the underground. The trap is otherwise harmless, and allows the player to regain control immediately. Alert Traps 1 and 2 send "hello" and "good-bye" messages respectively. Alert Trap 3 sends a message stating one is heading to the [[Union Room]], and Alert Trap 4 sends a message to come to one's location. Alert traps come in pastel colors when set by the player. Trap merchants will usually purchase Alert Traps for Pale Spheres.
*Alert Trap 1 - Stepping on this Trap sends greetings to everyone near you.
*Alert Trap 4 - Stepping on this Trap alerts everyone to gather around you.
traps create many bubbles around the player. After they all have been popped with the touch screen, the player can move again. The Bubble Trap makes more bubbles than the Foam Trap.
*Foam Trap - A Trap that releases bubbles. Pop the bubbles to get free.
*Bubble Trap - A Trap that releases a mass of bubbles. Pop them to get free.
The Confuse Trap causes the trapped player's character to ignore commands, and will walk randomly around until the trap wears off after 50 steps. The Reverse Trap reverses the player's controls for 20 steps.
*Reverse Trap - Stepping on this Trap reverses the victim's movements.
*Confuse Trap - Stepping on this Trap scrambles the victim's movements.
While it is not technically a trap per se, the [[Digger Drill]] is classified as a trap under the game's standards. It is only classified as a trap because it cannot be placed into the [[bag]] like a treasure, or be placed into the [[secret base]] like [[goods]]. It allows players to create a Secret Base.
*Digger Drill - A single-use drill to drill a hole in the wall for your Secret Base.
traps create a fire on the screen, which must be blown out using the DS's microphone. The fire will go back to full size if the blowing stops before they are out. After it has been blown out, the player can move again. The Fire Trap produces a larger flame than the Ember Trap.
*Ember Trap - This Trap releases immobilizing embers. Blow the embers away to get free.
*Fire Trap - This Trap releases billowing flames. Blow the flames away to get free.
traps create a hole beneath the player. The player is stuck in them until he or she moves him or herself around with the D-pad enough to get unstuck. Pit Traps take longer to get unstuck from than Hole Traps, and Crater Traps are the hardest to get out of.
*Hole Trap - A pit opens up underneath the Trap to immobilize the victim.
*Pit Trap - A huge pit opens up underneath the Trap to immobilize the victim.
*Fade trap - Stepping on this Trap makes the victim invisible.
Moving traps will move a player stepping on them in the indicated direction and they will be unable to stop themselves unless they hit into an obstacle or go too far. Stepping on a Hurl Trap will cause a player to move about twice the distance as a normal Move Trap.
*Move Trap ↑ - Stepping on this Trap sends the victim flying upwards.
*Move Trap → - Stepping on this Trap sends the victim flying to the right.
*Hurl Trap ↓ - Stepping on this Trap sends the victim flying far downward.
*Hurl Trap ← - Stepping on this Trap sends the victim flying far to the left.
traps create a flurry of leaves or flower petals, depending on which Trap is stepped on. Similar to the fire traps, after blowing away the plant with the microphone, the player can move again.
*Leaf Trap - This Trap releases immobilizing leaves. Blow the leaves away to get free.
*Flower Trap - This Trap releases many flowers. Blow the flowers away to get free.
*Radar Trap - Stepping on this renders the Radar useless for a while.
traps drop a rock on the player. After the rock has been smashed away using the touch screen, the player can move again. The Rock Trap's rock takes less hits to smash.
*Rock Trap - A Trap that makes blocking boulders. Break the boulders to get free.
*Rockfall Trap - A Trap that makes Big Boulders. Break the boulders to get free.
traps cause smoke to cover the touch screen. The player must rub the smoke off the screen in order to regain control. Big Smoke traps produce more smoke than Smoke traps.
*Smoke Trap - A Trap that releases obscuring smoke. The smoke can be rubbed away.
*Big Smoke Trap - A Trap that releases billowing smoke. The smoke can be rubbed away.
*Run Trap - Stepping on this Trap makes the victim run.
*Slow Trap - Stepping on this Trap slows the victim's foot speed.
*Warp Trap - Stepping on this Trap warps the victim far away.
*Hi-Warp Trap - Stepping on this Trap warps the victim far, far away.
