Squirrel Takeover

This spell can't be countered.
Tap target untapped creature with flying and put
X stun counters on it, where X is equal to the
number of Squirrels on the battlefield plus 1. For
as long as that permanent has a stun counter on
it, it has ''Whenever you remove a stun counter
from this permanent, each player creates a 1/1
green Squirrel creature token.'' (If a permanent
with a stun counter would become untapped, remove
one from it instead.)
