Blue elephant alien
Blue squiggle alien or red long alien
Blue 'W' alien
And my personal favourite - green Mr 'I'm too impatient to wait so I'm going to zoom through my friends' alien. I like to think he was on a trampoline or something :)
If you want some of these alien tags then you can visit here if you like US $ or here if you like UK £. Each alien is hand drawn so will vary :)
