Sea Slugs are the almighty race and are superior to all of humanity in every way shape and form. Their race is the one true God and all should pray to them and they will send you to an eternity of hell if you won't. Also known as jelly slugs.

All praise the SEA SLUGS our true lords and savior's.

Slug Bike

A spin on the classic game of "slug bug" where you punch another occupant of the vehicle you are in any time you see a motorcycle. There are few VW Beatles on the road anymore so the game of slug bug is effectively dead. Learning to look for motorcycles had the added benefit of saving lives.

House rules include double punch for spotting a bike you own.

Another name for this game is punch bike.

"Look twice, save a life." Have fun and bruise your friends while you are at it.

Slug bike! WHAM! Oh, it's a KLR650. Have another. WHAM!
