Octopus's Garden

( {t}: Add {u}. )
{t}, {1}{u}{u}: Tap target creature and put a stun
counter on it. Then, if there are eight or more creatures with stun counters on them, sacrifice
Octopus's Garden. If you do, create an 8/8 blue Octopus creature token.
I'd like to be, under the sea
In an octopus' garden, in the shade
