need new names, from the silver bullets to the leprechauns

my boys play roller hockey and it is typical to have a nickname on the back of your jersey.

last year, on the silver bullets, they were 'slapshot' and 'sniper'. this year, the silver bullets have changed their name to the leprechauns (shakes head, i don't know why) and the whole team wants to re-vamp their nicknames.

i have the worst ideas, but i'm hoping you can help me come up with some cool ones.
mine:
pot o' gold
end of the rainbow
three wishes
? something to do with shoes ?
erin go braugh
pigmy
sprite
fairy
mischief (the only one i like)
