Bubbles

Other creatures you control have vigilance.
Whenever another creature under your control dies, Bubbles gets +0/+1
At the beginning of your upkeep, create a food token if Bubbles toughness is greater than 5
If Bubbles were to be put into the graveyard from anywhere, you may pay 2 life. If you do, put Bubbles back in your library, 4th from the top.
