Yeah each fighter invited would have o keep it quite or be booted out. Have a massive payout like 1,000,000 to ensure this. Make it maybe like a lh weight tournament.
Get wand,chuck,rampage,tito,babalu,crocop (he can make weight he has before), and what the hell ace (same as crocop). Don't tell them who they are fighting hten whammo. Tournament style. Total random, like a street fight.
