Lick
Members of the tongue clan like to do one thing: lick. They go around licking everything to mark their tongue clan territory, you know? They even lick each other on the cheek by way of greeting.

な, ねぶ
None
Unfortunately, the tongue clan members also lick your nachos (な). You'd been saving those nachos! They were your travel rations. Now each and every nacho has been licked clean.
