Deep within the tunnel of the Underground, Tamers can find a place called the Arena. Although some onlookers that have wandered too deep can be found, it's unknown if they realize that what they see isn't just a toy bought from Electric Town. Here, Digimon can compete against one another. Depending on the fights, prizes may be offered. Mostly stuffed things, foods, coupons, and various pointless things, but when Tournaments come around, keep your eyes open for the grand prize.
