here's a special trick I made up on my own for kids lifting rocks 2 reds+ 1 orange and they will lift rocks that will improve there building skills it only works when there about 8 or 10 years old if they don't like rocks right away then redo the stew. 3 red flowers makes the kids use adult voices, two purple flowers and on red flower makes them healthier, green plus purple and black makes them clear there noses and throats.
