The waving snail is the lich which sometimes travels in finn's backpack as seen in "Mortal Folly".But he has the Enchiridden given to him in the episode "In Your Footsteps" so he will now have power to attack.

He has power,slaves,The Enchiridden,and travels in finn's backpack,but why isn't he attacking?He has all the power he needs and all he does is wait?Take him by suprise,possess Finn's body insted of the snail,have jake destroied and trap Finn,but he does nothing (he must be planning something big). Tell me what you think,leave a comment or some blitz and have fun for glob sake.
