Animal Jam made a new trading system, where you can trade up to 20 items for an item. Honestly, this is an update so many people have been waiting for. It's a tad bit strange having to trade 20 of your items for one time, and this will incontrovertibly change the value of certain items. But at least this will reduce trading scams. The only problem with this is that it will take a million years to find 20 of your items.
As you can see, the '+' will just keep adding on until you get 20 items. Pretty neat, hmm? However, I do feel that this update will encourage unfair trades.
