Actually, that seal toy looks interesting. It's something I'd try out at least once. Twice if it didn't hurt too much. ... or maybe if it did, depending.
Sherona, it's hypothesizing that the explanation for a fairly famous sea serpent sighting was a male whale swimming ... oddly. Maybe a couple of the sightings. They figure the ship hands saw a type of whale they weren't familiar with, took that as the head/frill of a sea serpent in 'olden' days... and the long, floppy, pointy, pink wang of a very excited whale was mistaken for a sea serpent tail.
That's the long story short. *nods*
