Hover your mouse over the Elves as they enter the room.
This will display the toys each elf needs to complete his bag of toys.
Next, click the green down arrow on one the toy chutes and pick the toy you want.
When a toy comes down the chute it needs to be painted the propper color.
Drag the toy over to the correct paint booth and it will be painted.
Then drag your freshly painted toy to the elf.
Fill all the elves bags before Christmas.
