A shortened word for a pesky insect, resistant to nuclear abuse, If you happen to partake, a joint smoked past its use

I am a wee little man, often dressed in green with a little green top hat... BUT luck is not with me, for I have Hansen's disease. Hmm. I seem to have lost feeling in my lucky arms...

You're after my pot of gold, I just know it, Where to hide it? Oh, I know a place you can't go, A place at the base of misted water when it's sunlit, A magical place you'll never reach at the bottom of a rainbow

My first is a scam A real flimflam My second is Number Two

I’m hidden in a playful grin, In little jokes that softly spin. I blush the cheeks, then slip away, But might come back another day. I make two hearts feel kind of shy, With giggly looks that pass right by.
