Items do not Move
Are you sure you bought the playable alien characters and not the alien topiary bushes (which look like them and are motionless decorations)?

Did you buy the green aliens for 15 dounts each? If so those are just topiarys which have no movement and just decorative. The aliens you have said you seen are acutal characters and only get released around halloween. If it is offered this year you will need to buy the ray gun for 150 doughnuts and shoot the alien out of the sky. The other was released last year part of the personal prizes from halloween 2013.
