I prefer normal Chinchompas due to the fact they're stackable (I hate having to release the lizards), and no one seems to be at those spots. I used to smoke the traps until I extinguished the torch, but xp seems to be similar without it. And about random events, 2 mazes in one day ! So unfair... I now carry 12/16 traps with me (4 at a time rocks !).
