when a Sulfur cube eats a potion, it should take on the effect forever

My thought process is that the potion gets stuck in the sulfur cube and it gets a little bloated but it keeps the effect FOREVER until its removed by the player. Although it can only have one at a time.

You give it levitation potion and it acts as a balloon when tied to a post by a lead. 

Give it Glow effect it will always glow (have to give the arrow of coarse)

Give it speed and the time it takes to launch to its new location it speed up

ETC ETC.

(Note: I know they said it Absorbs "Blocks" but i think this would just add to the fun also)
