Lord Cucumber

Lord Cucumber enters the battlefield with three
+1/+1 counters on it.
Whenever another creature you control dies, if
it had a +1/+1 counter on it, put a +1/+1 counter
on Lord Cucumber.
When Lord Cucumber dies, create an X/X black
and green Hydra creature token, where X is the
number of +1/+1 counters on Lord Cucumber.
