Fugu, Boss of the Sea

During your turn, Fugu is 8/8. During opponent's turn, she is 0/0 with a +1/+1 counter that can't be removed. Each time it is your opponent's turn, she receives a +1/+1 counter that can't be removed. Each time it is your opponent's turn, chose one: • Create a 3/1 sea urchin token. • Create a 1/1 turtle with "If this dies, this deals damage to any target equal to Fugu's power."
Trample, island-walk. Fish (or other sea-creatures) you control get +1/+1.
