Spined Penguin

Whenever a Penguin becomes blocked, that Penguin gets +1/+1 until end of turn for each creature blocking it.
"Inside my mind, there's a beautiful cup. A very beautiful, clear cup. And tiny drops kept falling into it, 'drip, drip, drip', slowly but steadily, everyday.
And today, I felt the cup had finally become
completely full."
-Kuu Penguin (Haibane Renmei)
