Shock Collar Question – October 13

Jeffrey is wearing the Shock Collar this morning!

Today’s Question: Only in Iceland, before any construction can begin on a building project, a special inspector needs to survey the site to make sure a very specific type of creature is NOT living “in or around” the site. This creature is said to be plentiful in Iceland, but no one has any proof that it really exists. What mythical or non-mythical creature am I talking about?
