Give it a touch of the Zee.

Game Instructions: It will be harder to do this convincingly if the skeleton already has other types of limbs. The Fins do not add Antiquity, Menace, or Amalgamy to your skeleton.

Unlocked with Skeleton: Limbs Needed, Fin Bones, Collected

Locked with Skeleton: Skulls Needed

Success

Might have come from anywhere

Fin bones could so easily be mistaken for bones of another type. But you wire them expertly in place, conveying a sense of the swimming animal.

•  You've gained 50 x Approximate Value of Your Skeleton in Pennies
•  You've lost 1 x Fin Bones, Collected
•  You've gained 1 x Skeleton: Fins
•  You've lost 1 x Skeleton: Limbs Needed

Failure

Might have come from anywhere

Fin bones could so easily be mistaken for bones of another type. You wire them in place to suggest a swimming animal, but the effect is not entirely happy.

•  You've gained 50 x Approximate Value of Your Skeleton in Pennies
•  You've lost 1 x Fin Bones, Collected
•  You've gained 1 x Skeleton: Fins
•  You've lost 1 x Skeleton: Limbs Needed
•  Your skeleton has become less believable. (Raises Skeleton: Self-Evident Implausibility by 2)
