Chinchompas (also known as grey chinchompas) are explosive animals that may be captured with box traps after completing Eagles' Peak. Killing them causes an explosion to occur, damaging the aggressive player by a maximum of 2 hitpoints. However, if it is done at a distance (with a bow, spell or halberd), the exploding chinchompa will not harm the player. This item is part of a class of explosive, multi-target ranged weapons.
Chinchompas can be found at the Piscatoris Hunter Area. Box trapping a Chinchompa requires a Hunter level of 53, with the chance of success being 6/255 at level 1, and 268/255 at level 99. Each chinchompa caught gives 198.4 experience.
A good spot is just south of the fairy ring (AKQ), where there is plenty of ruby harvests and chinchompas. Bring some butterfly jars and a butterfly net, while you wait for the traps, and catch some rubys while doing it. It will greatly improve your exp/h.
A fast but more attention-needing method of catching chinchompas is the "stand and shoot" method. The player should equip a bow and about 1000+ arrows, go to a crowded world, and figure out where one chinchompa respawns by killing one and seeing where it appears. Once the player knows the exact location where a chinchompa respawns, they should surround the square with their box traps. Then, as the chinchompa appears, it will either enter a trap, or it will dismantle at least one trap and hop away. If the chinchompa dismantles the traps, the player should immediately kill it with an arrow and set the traps up again as fast as possible. In about three to four seconds, the chinchompa will respawn again, and the player may repeat the process of "standing and shooting" if necessary. This method has been tested to be more experience per hour than the traditional "set-up traps and wait" method, because the player can just make the chinchompa respawn and make it more likely to enter a trap rather than wait while it wanders around.
