It's been well known penguins offer themselves up to seals.
Just read one of my fav stories...
A vacationing penguin is driving his through Arizona when he notices that the oil pressure light is on. He gets out to look and sees oil dripping out of the motor. He drives to the nearest town and stops at the first gas station.
After dropping the car off, the penguin goes for a walk around town. He sees an ice-cream shop and, being a penguin in Arizona, decides that something cold would really hit the spot. He gets a big dish of ice cream and sits down to eat. Having no hands he makes a real mess trying to eat with his flippers. After finishing his ice cream, he goes back to the gas station and asks the mechanic if he's found the problem. The mechanic looks up and says "It looks like you blew a seal."
"No no," the penguin replies, "it's just ice cream."
