A Flaaffy's pink, rubbery skin is extremely resistant to electricity. And it’s totally visible over much of its body as the electrical differential between a Flaaffy's fleece and body is so intense that it tears their fleece right out,, leaving them naked over much of their body. While Flaaffy wallow in their pink nakedness, the remaining fleece becomes even more powerfully imbued with electrical power and even more of it is torn out.
