Endeavor's Otter

Offspring {2} (You may pay an additional {2} as
you cast this spell. If you do, when this
creature enters, create a 1/1 token copy of it.)
Whenever you cast a noncreature spell, this creature deals 1 damage to each opponent.

In 1992, an otter was spotted in front of the Endeavor space shuttle, shortly before it's
launch.
