Start 6 Jobs
Only do 100 plushies per job.
Check back in 12-14 hours after starting the jobs and at least 3-4 of the jobs should be finished.
Ship the plushies to the store.
When you check back and they have been shipped to your store fire ALL employees.
Wait for all your plushies to sell and then rehire the employees. And start this process all over again.
This is how I got my trophy on my old account.
