Monkey Assistant is, in essence, a standard Deathmatch with one major addition: Monkeys! Every 30 or so seconds, a trumpet will signal the arrival of a band of well-armed monkeys. These simian soldiers teleport in to give the player in last place a little help, usually by hunting down whoever is currently in the lead and making their life hell.
In TS2, If Monkey was shown in a certain botset, he will be replaced with Jungle Queen instead.
If you played as a monkey on your last arcade game, you can be that monkey because it sets it as your player.
