Jabbering School

As an additional cost to cast Jabbering School,
sacrifice X Fish, Whale, Merfolk, Octopus, and
Kraken creatures.
Jabbering School enters the battlefield with X
+1/+1 counters on it.
Whenever Jabbering School would take damage,
prevent it and remove a +1/+1 counter instead.
Then create a 2/2 blue and black Fish Horror
creature token.
