Walkerbear read the instructions very carefully and gave Oscar and Alfred details of what to do. Apparently they needed to push out the pieces of coloured foam and put them together in a special order and the pieces made one of the insects shown on the front.
First of all, and very carefully, in the correct order, the green pieces had to be pushed out of the sheets of foam and then slotted together. Walkerbear, being in charge of instructions, told Oscar to push out piece 1 and showed him from the instruction sheet what the shape was. Then Alfred pushed out piece 2 and slotted the pieces together.
