3.
A fecal specimen which straddles the porcelain coast, partially in and partially out of the water. An amphibian is neither a floater nor a sinker, until forced back into the icy depths. Usually type 3 or 4 on the Bristol Stool Scale.

Amphibians rarely go undetected because they are very heavy breathers. But if they do go unnoticed and manage to survive the whirlpool they are likely to expire on shore and become a sticktite.
