{2}{B}, Exile Barbed Cocoon from your graveyard: Create two 1/1 green Insect creature tokens. Activate only as a sorcery.

Barbed Reef enters tapped. When it does, it explores. (Reveal the top card of your library. Put that card into your hand if it's a land. Otherwise, put a +1/+1 counter on this, then you may put that card into your graveyard.)
{T}: Add {B}.
{4}{B}: Barbed Reef becomes a Jellyfish creature. (This effect lasts indefinitely.)

Defender (This creature can't attack.)
