Grumpy Snail (character)

The Grumpy Snail is the main character of the eponymous piece of music written for the Holophonor. The holographic projection depicts the snail crawling on a tree branch towards the audience, but what (if anything) else the snail does past the beginning of the piece is unknown.

Monster Snail
Despite its name, the snail isn't always grumpy. Its temperament seems to depend on the skill of the holophonor player. Fry's initial lack of skill would turn him into a monster that terrified his audience. But, after Fry obtained the Robot Devil's hands, the performances improved, and the snail became much more distinguished and professional in appearance, becoming a fixture in Fry's music and even having a speaking role in an advertisement for Fry's Greatest Holophonor Hits.
