There should be a metal detector VIP. Comes in these colors:
Red,Black,Silver,Purple,Orange.
The detector is held with two hands while players scan the floor. Random amounts of graalats can be found in the ground across era. When you find a spot,your metal detector beeps. Then your player will "grab" that spot and pull out some graalats. Least you can find is 35 graalats and the most would be 350 graalats. Sounds like a good idea but needs a bit improving. ^_^
