Flea (Franchise)

Fleas are insects mentioned briefly in How to Train Your Dragon franchise.

Description
Fleas are wingless insects from the Siphonaptera. They are parasites of mammals and birds which consume their blood. Because of this, they are vectors of different diseases such as Murine typhus and Bubonic plague.

Even though they are wingless, their hind legs are very long and powerful, allowing them to jump 50 times their body length. They have claws at the end of each limb to prevent being dislodged.

Function
Fleas do not have a function nor in the franchise, nor in the real life.
