FAIRY 

"The fairy is a small decorative beast of little intelligence. Often used or conjured by wizards for decoration, the fairy generally inhabits woodlands or glades. Ranging in height from one to five inches, the fairy has a minute humanoid body, head and limbs but sports large insect-like wings, which may be transparent or multi-coloured, according to type."

ERUMPET

"The Erumpet is a large grey African beast of great power. Weighing up to a tonne, the Erumpet may be mistaken for a rhinoceros at a distance. It has a thick hide that repels most charms and curses, a large, sharp horn upon its nose and a long, rope-like tail."

-J.K. Rowling
