Grog Strongjaw Grand Poobah

Grog Strongjaw Grand Poobah enters the battlefield with four +1/+1 counters on it.
Whenever another creature enters the battlefield
under your control, put a +1/+1 counter on
Grog. Then if that creature's power is greater
than Grog's power, put another +1/+1
counter on Grog.
