A Clabbert is an arboreal creature resembling a cross between a monkey and a frog (FB).
- Native to the Southern United States, but exported abroad (FB).
- It has mottled green smooth skin, short horns, and a wide mouth. Long arms and webbed hands and feet allow it to move gracefully through the trees (FB).
- On the Clabbert's forehead is a large pustule which flashes red for the approach of danger, and American wizards once used them as early warning devices for Muggles. But the International Confederation of Wizards put a stop to the use of the Clabbert, which actually attracted too much attention, as Muggles were drawn to the sight of what they thought were leftover Christmas lights flashing in trees (FB).
"clabber" Southern Scotch-Irish dialect word for mud or wet clay; Also refers to milk that curdles at room temperature into something similar to yogurt. There is a famous American baking powder called "Clabber Girl", alluding to cooks who once made biscuits with clabber.
