Algae Pool Merfolk

Sea Shanty 1 (Sing or hum a verse and chorus of "Drunken Sailor"; if you do, put a +1/+1 counter on this creature. Cannot exceed 99 +1/+1 counters from this source. Do this only as a Sorcery, and only once each turn.)
The algae grants two boons: Life, in the form of sustenance; and safety, in the form of concealment.
