I dunno if this will work...
There are 10 boxes all different colors. Each one has a pet in it. Pay 150 gold for any box. 6 of the boxes are random pets I dont want(2-4 traits). 2 are themed, but one of the themed dont have many traits. 1 is empty but you get 105 coins from it. The last one is level 30 or higher. There isnt always one, but sometimes there will be an essence in the box...

Here are the boxes, once one has been claimed I will cross it out. You can only pick 3 boxes per round.
Box 1(pink)
Box 2(brown)
Box 3(blue)
Box 4(Blue)
Box 5(sparkly?)
Box 6(black)
Box 7(magenta)
Box 8(brown)
Box 9(white)
Box 10(blue)
