well go to your time and set it to 2.59PM and wait a minute, then go into your shop to see if you have a UFO in your shop, it looks kinda like a hat with a line coming out of it, if you dont get it in your shop, keep trying until you do get it, they are pretty haved to get, my tama is gen 5 and ive only had it in my shop 2 times! one time i bought it, the other i couldnt afford it in time...
I bought a U.F.O for 5000pts but i just wanted to let you know you can also set ur time to 6:59 and wait till 7:00 and ur shop will change hope i helped a bit
