No holding back. Deck it out with bubble machines, sparklers, Urf statues, fish, and large golden machinegun columns. If someone gets a pentakill, the map flips a sh*t and the machineguns fire in a blaze of righteous Urf glory. If a champion has an Urf skin equipped, the machineguns go off as you pass on your way to lane.
I have dreams. This would be amazing.
