Snails

Snails is a unicorn pony who is often seen in the company of his friend Snips.

Personality
Snails is most likely named so due to his overall slow nature and mind.

History
Snails is first seen in the episode, Boast Busters, admiring the bragging traveling magician, Trixie, along with Snips.

He has a non-speaking cameo in Call of the Cutie, attending the Cute-ceañera where he took the first bite of cake (much to the annoyance of Diamond Tiara.)

Snails is also in the episode Show Stoppers doing a magic trick for the talent show with Snips.

Trivia
Both Snails as well as partner-in-crime Snips are named after the traditional nursery rhyme What Are Little Boys Made Of?. In the original rhyme, the verse goes -
 * What are little boys made of? What are little boys made of? Snips and Snails and Puppy Dogs' tails. That's what little boys are made of.

It is interesting to note that Lauren Faust's first production, the Powerpuff Girls, uses these ingredients to create the villians The Rowdyruff Boys. The second verse of the nursery rhyme also mentions that Sugar, Spice and everything Nice as what little GIRLS are made of.

It seems that his horn is only a light source. He used it as such in the Ursa's cave.
