A shamrunk is an elf like entity who is so very small he can sit very easially in the palm of your hand. There are always twelve in a pack, or rather stack, for reason unknown they create stacks of 12 by getting on eachothers shoulders then exploding outwards scattering all about. They have woody brown skin with long noses and blue hats. Generally you can only see them if you get huff, ALOT, of spray paint, like alot alot, so much that its quite possible you'll end up in the emergency room alot.
Grandma: Those rascals were as rambunctious as a stack of shamrunks.
